Interracial sperm competition

Description:You could also look at sperm content from real-life interracial couples, but there could be confounding factors. Holidic diets were used which allowed for specific protein and carbohydrate measurements to be taken, giving it credibility. Regarding sexual dimorphism among primates, humans falls into an intermediate group with moderate sex differences in body size but relatively large testes. He will then drive away any males that come near and this will greatly increase his chances of copulation with any female that comes to that area. There is a risk of cuckoldry of some sort since a rival male can successfully court the female that the male originally courting her could not do. These ratios and results are not consistent with many other species and even conflict with some.
