Document Summary
Potential for inheritance of bad alleles and phenotypes from one or the other parent. Potentially fitness could be lower than an organism that is asexual (because the number of offspring will be lower) Investment in morphology or behavior to get a mate. Increased potential risk pregnancy, stds, not being vigilant for predators or food during copulation. Cannot pass on all of the alleles one parent possesses. Sexual reproduction increases the likelihood that some offspring will be appropriately equipped to survive. Differential reproduction success due to variation among individuals in success at getting mates. Ability or inability to a get a mate. Sexual dimorphism when males and females look different because of sexual selection. Hooking together within the female"s reproductive tract to increase the likelihood of that male to fertilize the female"s egg. Mothers make a larger parental investment" in offspring than fathers.
