, offspring are the young born 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 child
ren (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 son
s and female children are daughter
s (see kinship and descent
). 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 mother, which is also known as the parent generation. Each of these offspring contains numerous genes which have coding for specific tasks and properties. Males and females both contribute equally to the genotypes of their offspring, in which gametes fuse and form. An important aspect of the formation of the parent offspring is the chromosome, which is a structure of DNA which contains many genes.
To focus more on the offspring and how it results in the formation of the f1 generation, is an inheritance called sex-linkage, which is a gene which is located on the sex chromosome and patterns of these inheritance differ in both male and female. The explanation that proves the theory of the offspring having genes from both parent generations, is proven through a process called crossing-over, which consists of taking genes from the male chromosomes and genes from the female chromosome, resulting in a process of meiosis
occurring, and leading to the splitting of the chromosomes evenly. Depending on which genes are dominantly expressed in the gene will result in the sex of the offspring. The female will always give an X chromosome, whereas the male, depending on the situation, will either give an X chromosome or a Y chromosome. If a male offspring is produced, the gene will consist of an X and a Y chromosome. If two X chromosomes are expressed and produced, it produces a female offspring.
Cloning is the production of an offspring which represents the identical genes as its parent. Reproductive cloning begins with the removal of the nucleus from an egg, which holds the genetic material. In order to clone an organ, a stem cell is to be produced and then utilized to clone that specific organ. A common misconception of cloning is that it produces an exact copy of the parent being cloned. Cloning copies the DNA/genes of the parent and then creates a genetic duplicate. The clone will not be a similar copy as he or she will grow up in different surroundings from the parent and may encounter different opportunities and experiences. Although mostly positive, cloning also faces some setbacks in terms of ethics and human health. Though cell division and DNA replication is a vital part of survival, there are many steps involved and mutations can occur with permanent change in an organism's and their offspring's DNA.
Some mutations can be good as they result in random evolution periods in which may be good for the species, but most mutations are bad as they can change the genotypes of offspring, which can result in changes that harm the species.
