  2. Heredity - Wikipedia

    en.wikipedia.org/wiki/Heredity

    Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.

    Also called functionalism. The Darwinian view that many or most physiological and behavioral traits of organisms are adaptations that have evolved for specific functions or for specific reasons (as opposed to being byproducts of the evolution of other traits, consequences of biological constraints, or the result of random variation). adaptive radiation The simultaneous or near-simultaneous ...

  4. Parthenogenesis - Wikipedia

    en.wikipedia.org/wiki/Parthenogenesis

    Obligate parthenogenesis is the process in which organisms exclusively reproduce through asexual means. [39] Many species have transitioned to obligate parthenogenesis over evolutionary time. Well documented transitions to obligate parthenogenesis have been found in numerous metazoan taxa, albeit through highly diverse mechanisms.

  5. Reproduction - Wikipedia

    en.wikipedia.org/wiki/Reproduction

    Reproduction (or procreation or breeding) is the biological process by which new individual organisms – "offspring" – are produced from their "parent" or parents. There are two forms of reproduction: asexual and sexual. In asexual reproduction, an organism can reproduce without the involvement of another organism.

  6. Offspring - Wikipedia

    en.wikipedia.org/wiki/Offspring

    In biology, offspring are the young creation of living organisms, produced either by sexual or asexual reproduction. Collective offspring may be known as a brood or progeny. This can refer to a set of simultaneous offspring, such as the chicks hatched from one clutch of eggs, or to all offspring produced over time, as with the honeybee.

  7. Species - Wikipedia

    en.wikipedia.org/wiki/Species

    The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. [2] [3] [4] About 14% of these had been described by 2011. [4] All species (except viruses) are given a two-part name, called a "binomial". The first part of a binomial is the genus to which the species belongs.

    This is typical in animals, though the number of chromosome sets and how that number changes in sexual reproduction varies, especially among plants, fungi, and other eukaryotes. [ 2 ] [ 3 ] In placental mammals , sperm cells exit the penis through the male urethra and enter the vagina during copulation , [ 4 ] [ 5 ] while egg cells enter the ...
