Photo: @Robert Clark | ​A brown #peafowl or a #peacock as they are commonly known shows the display that is used to attract females for mating.
#CharlesDarwin theorized in an expanded writing in his second book, the #DescentOfMan. The struggle is likewise between the individuals of the same sex, in order to excite or charm those of the opposite sex, generally the females, which no longer remain passive, but select the more agreeable partners." Sexual Selection being the ability of male and female organisms to exert #SelectiveForce

In regards to mating activity the strongest driver of sexual selection is gamete size. #eggs are bigger then #sperm and females produce fewer #gametes then males. Eggs are a bigger investment and therefor females being choosy about the traits that will be passed on by males.

The #peacock reproductive success and the survival of her chicks is partly dependent on the genotype of the mate. Females generally have more to lose when mating with an inferior male due to her gametes being more costly then the male's.
