Sexual reproduction involves the combining and mixing of genetic traits: specialized cells known as gametes combine to form offspring that inherit traits from each parent.
The gametes produced by an organism define its sex: males produce small gametes (e.g.
Many species, both plants and animals, have sexual specialization, and their populations are divided into male and female individuals.
Conversely, there are also species in which there is no sexual specialization, and the same individuals both contain masculine and feminine reproductive organs, and they are called hermaphrodites. The reason for the evolution of sex, and the reason(s) it has survived to the present, are still matters of debate.
Gametes can be identical in form and function (known as isogamy), but, in many cases, an asymmetry has evolved such that two different types of gametes (heterogametes) exist (known as anisogamy).
Physical differences are often associated with the different sexes of an organism; these sexual dimorphisms can reflect the different reproductive pressures the sexes experience.This mode of reproduction is called asexual, and it is still used by many species, particularly unicellular, but it is also very common in multicellular organisms, including many of those with sexual reproduction.In sexual reproduction, the genetic material of the offspring comes from two different individuals.Life has evolved from simple stages to more complex ones, and so have the reproduction mechanisms.Initially the reproduction was a replicating process that consists in producing new individuals that contain the same genetic information as the original or parent individual.Some bacteria use conjugation to transfer genetic material between cells; while not the same as sexual reproduction, this also results in the mixture of genetic traits.Tags: Adult Dating, affair dating, sex dating
