"Good morning. First things first: grades for your midterm." Daniel reads down a list.

"Today, we're looking at nonrandom mating and it's influence on population genetics.

The result of nonrandom mating is that some individuals have more opportunity to mate than others and thus produce more offspring (and more copies of their genes) than others. Random mating works against evolutionary change by guaranteeing that the genes of a population are thoroughly mixed among the members of the next generation.

Random mating is unlikely to occur for a variety of reasons. One is that it is simply easier to mate with a nearby individual, as opposed to one that is farther away. Also, especially in animals, individuals compete for mates and active selection of mating partners occurs. This goes directly against the concept of randomness.

Any thoughts on how random and nonrandom mating is involved in population genetics?

Monday's homework, on my desk, please.  For tonight, I want you to look up the Hardy-Weinberg equilibrium equation. That's all, thank you, and I'll see you on Friday."
