Heteropaternal Superfecundation
Superfecundation is the fertilization of two or more ova from the same cycle by sperm from separate acts of sexual intercourse, which can lead to twin babies from two separate biological fathers. The term superfecundation is derived from fecund, meaning the ability to produce offspring. Homopaternal superfecundation is fertilization of two separate ova from the same father, leading to fraternal twins, while heteropaternal superfecundation is a form of atypical twinning where, genetically, the twins are half siblings – sharing the same mother, but with different fathers. Conception Sperm cells can live inside a female's body for up to five days, and once ovulation occurs, the egg remains viable for 12–48 hours before it begins to disintegrate. Superfecundation most commonly happens within hours or days of the first instance of fertilization with ova released during the same cycle. Ovulation is normally suspended during pregnancy to prevent further ova becoming fertilized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ovum
The egg cell, or ovum (plural ova), is the female reproductive cell, or gamete, in most anisogamous organisms (organisms that reproduce sexually with a larger, female gamete and a smaller, male one). The term is used when the female gamete is not capable of movement (non- motile). If the male gamete ( sperm) is capable of movement, the type of sexual reproduction is also classified as oogamous. A nonmotile female gamete formed in the oogonium of some algae, fungi, oomycetes, or bryophytes is an oosphere. When fertilized the oosphere becomes the oospore. When egg and sperm fuse during fertilisation, a diploid cell (the zygote) is formed, which rapidly grows into a new organism. History While the non-mammalian animal egg was obvious, the doctrine ''ex ovo omne vivum'' ("every living nimal comes froman egg"), associated with William Harvey (1578–1657), was a rejection of spontaneous generation and preformationism as well as a bold assumption that mammals also reprodu ...

Castor And Pollux
Castor; grc, Κάστωρ, Kástōr, beaver. and Pollux. (or Polydeukes). are twin half-brothers in Greek and Roman mythology, known together as the Dioscuri.; grc, Διόσκουροι, Dióskouroi, sons of Zeus, links=no, from ''Dîos'' ('Zeus') and '' koûroi'' ('boys'). Their mother was Leda, but they had different fathers; Castor was the mortal son of Tyndareus, the king of Sparta, while Pollux was the divine son of Zeus, who raped Leda in the guise of a swan. The pair are thus an example of heteropaternal superfecundation. Though accounts of their birth are varied, they are sometimes said to have been born from an egg, along with their twin sisters Helen of Troy and Clytemnestra. In Latin the twins are also known as the Gemini (literally "twins") or Castores, as well as the Tyndaridae or Tyndarids.. Pollux asked Zeus to let him share his own immortality with his twin to keep them together, and they were transformed into the constellation Gemini. The pair were rega ...

New Jersey
New Jersey is a state in the Mid-Atlantic and Northeastern regions of the United States. It is bordered on the north and east by the state of New York; on the east, southeast, and south by the Atlantic Ocean; on the west by the Delaware River and Pennsylvania; and on the southwest by Delaware Bay and the state of Delaware. At , New Jersey is the fifth-smallest state in land area; but with close to 9.3 million residents, it ranks 11th in population and first in population density. The state capital is Trenton, and the most populous city is Newark. With the exception of Warren County, all of the state's 21 counties lie within the combined statistical areas of New York City or Philadelphia. New Jersey was first inhabited by Native Americans for at least 2,800 years, with the Lenape being the dominant group when Europeans arrived in the early 17th century. Dutch and Swedish colonists founded the first European settlements in the state. The British later seized contro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monochorionic
Monochorionic twins are monozygotic (identical) twins that share the same placenta. If the placenta is shared by more than two twins (see multiple birth), these are monochorionic multiples. Monochorionic twins occur in 0.3% of all pregnancies. Seventy-five percent of monozygotic twin pregnancies are monochorionic; the remaining 25% are ''dichorionic diamniotic''. If the placenta divides, this takes place before the third day after fertilization. Amniocity and zygosity Monochorionic twins generally have two amniotic sacs (called Monochorionic-Diamniotic "MoDi"), but sometimes, in the case of monoamniotic twins (Monochorionic-Monoamniotic "MoMo"), they also share the same amniotic sac. Monoamniotic twins occur when the split takes place after the ninth day after fertilization. Monoamniotic twins are ''always'' monozygotic (identical twins).Pregnancy-Info -- > Monoamniotic TwinsRetrieved on July 9, 2009 Monochorionic-Diamniotic twins are ''almost always'' monozygotic, with a fe ...

Diamniotic
The amniotic sac, also called the bag of waters or the membranes, is the sac in which the embryo and later fetus develops in amniotes. It is a thin but tough transparent pair of membranes that hold a developing embryo (and later fetus) until shortly before birth. The inner of these membranes, the amnion, encloses the amniotic cavity, containing the amniotic fluid and the embryo. The outer membrane, the chorion, contains the amnion and is part of the placenta. On the outer side, the amniotic sac is connected to the yolk sac, the allantois, and via the umbilical cord, the placenta. The yolk sac, amnion, chorion, and allantois are the four extraembryonic membranes that lie outside of the embryo and are involved in providing nutrients and protection to the developing embryo. They form from the inner cell mass; the first to form is the yolk sac followed by the amnion which grows over the developing embryo. The amnion remains an important extraembryonic membrane throughout prenatal deve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philammon
In Greek mythology, Philammon (Ancient Greek: Φιλάμμων) was an excellent musician, a talent he received from his father Apollo.

But Philammon refused to take her into his house as his wife and for being ashamed of the pregnancy, the girl left Peloponnese and came to the Akte (shore) where she gave birth to a boy, Thamyris. Philammon was said to have established the tradition of the hymns celebrating the births of Artemis and Apollo, written by himself, being performed by choruses of girls at Delphi. He was the second winner of the most ancient singing contest at Delphi, after Chrysothemis and before his son Thamyris. Some ascribe to him the foundation of the Lernaean my ...

Heracles ( ; grc-gre, Ἡρακλῆς, , glory/fame of Hera), born Alcaeus (, ''Alkaios'') or Alcides (, ''Alkeidēs''), was a divine hero in Greek mythology, the son of Zeus and Alcmene, and the foster son of Amphitryon.By his adoptive descent through Amphitryon, Heracles receives the epithet Alcides, as "of the line of Alcaeus", father of Amphitryon. Amphitryon's own, mortal son was Iphicles. He was a great-grandson and half-brother (as they are both sired by the god Zeus) of Perseus, and similarly a half-brother of Dionysus. He was the greatest of the Greek heroes, the ancestor of royal clans who claimed to be Heracleidae (), and a champion of the Olympian order against chthonic monsters. In Rome and the modern West, he is known as Hercules, with whom the later Roman emperors, in particular Commodus and Maximian, often identified themselves. The Romans adopted the Greek version of his life and works essentially unchanged, but added anecdotal detail of their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
