Document Summary

2013: the frequency between a generation is changing, changes can happen as, simple allele traits. There are different variations (usually evenly distributed) Mutation (crossing over) causes a huge amount of variation. Plants use polyploidy to cause variation: what happens when you have a small amount of population, sampling can affect the predicted outcome between population genetics and. If we only sample a small sice, we will not be able (more than likely) to get the real amount. The founder affect: the founding population causes a variability through the existed population, less variation, ex. New france (quebec: one founding group is subsided and is left to colonise other country, small population + less variability = less distribution of alleles that causes of diseases/heritable diseases. If we try to repopulate species, we are repopulating a small subsample of the genetic variability. Random mating: no selective choices, non-random mating inbreeding, ex.
