Notes on Maintaining genetic Variation
Neutral Variating, Allele that has no effect on fitness, but if an incident occurs a mutation can lead to a successfull usage of this allele
Sexual reproduction, independent assortment, crossing occurs with genetic recombination, random fertilization.
Frequency dependent selection, where polymorphism is maintained when the fitness of a genotype depends on its frequency in a population. ex. left mouth scale eating fish vs. right mouth scale eating fish
Environmental variation, variations can occur at different locations.
