Document Summary

Examine how it changes so we can look at how evolution works (changes in alleles across generations) Larger circumstances make it so that some breed more than others (natural selection and random incidents) Hardy weinburg eq. - everything now has come to a stop because there are no changes. When that isn"t happening, that means someone is doing better than expected and there is change going on. Even without mutation, genetic drift happens and all start to become the same in small populations. Founder effect: when you separate part of the population, just by chance the alleles are super different. Environment plays a role in the phenotype too. A single locus can control more than one trait (pleiotrophy)
