The answer to this question would be choice C. the existence of homologous structures
---------------------------------------------------------------------------------------------------------Explanation: Basically, homologous structures are structures that are similar to each other, but are found in different organisms (or animals). In other words, they are structures in common between species. Moreover, this homologous structures basically show that organisms come from a common ancestor and have changed over time.
Meisos involve halving the genetic material of a cell to form garments. The gametes of two parents fuse to form a zygote that6 returns the genetic material to normal ploidy so it can develop into offspring. The fusion of two gametes is called fertilization.
