Parent Teacher Organization
A parent is a caregiver of the offspring in their own species. In humans, a parent is the caretaker of a child (where "child" refers to offspring, not necessarily age). A ''biological parent'' is a person whose gamete resulted in a child, a male through the sperm, and a female through the ovum. Biological parents are first-degree relatives and have 50% genetic meet. A female can also become a parent through surrogacy. Some parents may be adoptive parents, who nurture and raise an offspring, but are not biologically related to the child. Orphans without adoptive parents can be raised by their grandparents or other family members. A parent can also be elaborated as an ancestor removed one generation. With recent medical advances, it is possible to have more than two biological parents. Examples of third biological parents include instances involving surrogacy or a third person who has provided DNA samples during an assisted reproductive procedure that has altered the recipients' gen ...

Offspring
In biology, offspring are the young creation of living organisms, produced either by a single organism or, in the case of sexual reproduction, two organisms. Collective offspring may be known as a brood or progeny in a more general way. This can refer to a set of simultaneous offspring, such as the chicks hatched from one clutch of eggs, or to all the offspring, as with the honeybee. Human offspring ( descendants) are referred to as children (without reference to age, thus one can refer to a parent's " minor children" or " adult children" or " infant children" or " teenage children" depending on their age); male children are sons and female children are daughters (see kinship). Offspring can occur after mating or after artificial insemination. Offspring contains many parts and properties that are precise and accurate in what they consist of, and what they define. As the offspring of a new species, also known as a child or f1 generation, consist of genes of the father and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overprotective
A helicopter parent (also called a cosseting parent or simply a cosseter) is a parent who pays extremely close attention to a child's or children's experiences and problems, particularly at educational institutions. Helicopter parents are so named because, like helicopters, they "hover overhead", overseeing every aspect of their child's life constantly. A helicopter parent is also known to strictly supervise their children in all aspects of their lives, including in social interactions. Etymology The metaphor appeared as early as 1969 in the bestselling book ''Between Parent & Teenager'' by Dr. Haim Ginott, which mentions a teen who complains: "Mother hovers over me like a helicopter..." The term "helicopter parent" has been in use since the late 1980s. It subsequently gained wide currency when American academic administrators began using it in the early 2000s as the oldest millennials began reaching college age. Their baby-boomer parents earned notoriety for practices such as call ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genetic Chimera
A genetic chimerism or chimera ( ) is a single organism composed of cells with more than one distinct genotype. In animals, this means an individual derived from two or more zygotes, which can include possessing blood cells of different blood types, subtle variations in form (phenotype) and, if the zygotes were of differing sexes, then even the possession of both female and male sex organs. Animal chimeras are produced by the merger of two (or more) embryos. In plant chimeras, however, the distinct types of tissue may originate from the same zygote, and the difference is often due to mutation during ordinary cell division. Normally, genetic chimerism is not visible on casual inspection; however, it has been detected in the course of proving parentage. Another way that chimerism can occur in animals is by organ transplantation, giving one individual tissues that developed from a different genome. For example, transplantation of bone marrow often determines the recipient's ensuin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sperm
Sperm is the male reproductive cell, or gamete, in anisogamous forms of sexual reproduction (forms in which there is a larger, female reproductive cell and a smaller, male one). Animals produce motile sperm with a tail known as a flagellum, which are known as spermatozoa, while some red algae and fungi produce non-motile sperm cells, known as spermatia. Flowering plants contain non-motile sperm inside pollen, while some more basal plants like ferns and some gymnosperms have motile sperm. Sperm cells form during the process known as spermatogenesis, which in amniotes ( reptiles and mammals) takes place in the seminiferous tubules of the testes. This process involves the production of several successive sperm cell precursors, starting with spermatogonia, which differentiate into spermatocytes. The spermatocytes then undergo meiosis, reducing their chromosome number by half, which produces spermatids. The spermatids then mature and, in animals, construct a tail, or flagellum, ...

Parenting
Parenting or child rearing promotes and supports the physical, emotional, social, spiritual and intellectual development of a child from infancy to adulthood. Parenting refers to the intricacies of raising a child and not exclusively for a biological relationship. The most common caretaker in parenting is the father or mother, or both, the biological parents of the child in question. However, a surrogate parent may be an older sibling, a step-parent, a grandparent, a legal guardian, aunt, uncle, other family members, or a family friend. Governments and society may also have a role in child-rearing or upbringing. In many cases, orphaned or abandoned children receive parental care from non-parent or non-blood relations. Others may be adopted, raised in foster care, or placed in an orphanage. Parenting skills vary, and a parent or surrogate with good parenting skills may be referred to as a ''good parent''. Parenting styles vary by historical period, race/ethnicity, social c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Childbirth
Childbirth, also known as labour and delivery, is the ending of pregnancy where one or more babies exits the internal environment of the mother via vaginal delivery or caesarean section. In 2019, there were about 140.11 million births globally. In the developed countries, most deliveries occur in hospitals, while in the developing countries most are home births. The most common childbirth method worldwide is vaginal delivery. It involves four stages of labour: the shortening and opening of the cervix during the first stage, descent and birth of the baby during the second, the delivery of the placenta during the third, and the recovery of the mother and infant during the fourth stage, which is referred to as the postpartum. The first stage is characterized by abdominal cramping or back pain that typically lasts half a minute and occurs every 10 to 30 minutes. Contractions gradually becomes stronger and closer together. Since the pain of childbirth correlates with contractions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pregnancy
Pregnancy is the time during which one or more offspring develops ( gestates) inside a woman's uterus (womb). A multiple pregnancy involves more than one offspring, such as with twins. Pregnancy usually occurs by sexual intercourse, but can also occur through assisted reproductive technology procedures. A pregnancy may end in a live birth, a miscarriage, an induced abortion, or a stillbirth. Childbirth typically occurs around 40 weeks from the start of the last menstrual period (LMP), a span known as the gestational age. This is just over nine months. Counting by fertilization age, the length is about 38 weeks. Pregnancy is "the presence of an implanted human embryo or fetus in the uterus"; implantation occurs on average 8–9 days after fertilization. An '' embryo'' is the term for the developing offspring during the first seven weeks following implantation (i.e. ten weeks' gestational age), after which the term ''fetus'' is used until birth. Signs an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Postpartum Baby2
The postpartum (or postnatal) period begins after childbirth and is typically considered to end within 6 weeks as the mother's body, including hormone levels and uterus size, returns to a non-pregnant state. The terms puerperium, puerperal period, or immediate postpartum period are commonly used to refer to the first six weeks following childbirth. The World Health Organization (WHO) describes the postnatal period as the most critical and yet the most neglected phase in the lives of mothers and babies; most maternal and infant mortality, newborn deaths occur during this period. In scientific literature, the term is commonly abbreviated to P''x'', where ''x'' is a number; for example, "day P5" should be read as "the fifth day after birth". This is not to be confused with the medical nomenclature that uses G P to stand for number and outcomes of pregnancy (gravidity and parity). A female giving birth in a hospital may leave as soon as they are medically stable, which can be as ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foster Parent
Foster care is a system in which a minor has been placed into a ward, group home (residential child care community, treatment center, etc.), or private home of a state-certified caregiver, referred to as a "foster parent" or with a family member approved by the state. The placement of the child is normally arranged through the government or a social service agency. The institution, group home, or foster parent is compensated for expenses unless with a family member. In some states, relative or "Kinship" caregivers of children who are wards of the state are provided with a financial stipend. The state, via the family court and child protective services agency, stand ''in loco parentis'' to the minor, making all legal decisions while the foster parent is responsible for the day-to-day care of the minor. Scholars and activists are concerned about the efficacy of the foster care services provided by NGOs. Specifically, this pertains to poor retention rates of social workers. Poor ...

Stepmother
A stepmother, stepmum or stepmom is a non-biological female parent married to one's preexisting parent. A stepmother-in-law is a stepmother of one's spouse. Children from her spouse's previous unions are known as her stepchildren. Culture Stepparents (mainly stepmothers) may also face some societal challenges due to the stigma surrounding the "evil stepmother" character. Morello notes that the introduction of the "evil stepmother" character in the past is problematic to stepparents today, as it has created a stigma towards stepmothers. The presence of this stigma can have a negative impact on stepmothers' self-esteem. Fiction In fiction, stepmothers are often portrayed as being wicked and evil. The character of the wicked stepmother features heavily in fairy tales; the most famous examples are ''Cinderella'', ''Snow White'' and ''Hansel and Gretel''. Stepdaughters are her most common victim, and then stepdaughter/stepson pairs, but stepsons also are victims as in '' The Jun ...

Gene
In biology, the word gene (from , ; "...Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a basic unit of heredity and the molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and noncoding genes. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. These genes make up different DNA sequences called genotypes. Genotypes along with environmental and developmental factors determine what the phenotypes will be. Most biological traits are under the influence of polygenes (many different genes) as well as gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
