Gametes in biology
WebApr 11, 2024 · Ok. If one wnats to believe gametes are the only truly evolutionary, behaviorally and structurally relevant part of an organism's sex biology (thus its "sex") that is fine, but admit it is a belief and not a serious take on organismal biology. A gamete is a haploid cell that fuses with another haploid cell during fertilization in organisms that reproduce sexually. Gametes are an organism's reproductive cells, also referred to as sex cells. In species that produce two morphologically distinct types of gametes, and in which each individual produces only one type, a female is any individual that produces the larger type of gamete—called an ov…

WebGametes, also known as reproductive cells or, more often, sex cells, are cells that are intended to merge during the process of sexual reproduction. They are the most important cells in the reproductive cycle.

Gregor Mendel’s law of segregation states that the two alleles for each trait segregate, or separate, during the formation of gametes, and that during the formation of new zygotes, the alleles will combine at random with other alleles. The law of segregation ensures that a parent, with two copies of each gene ...
