wild-type allele {Ans: A prevalent allele in a population. Dominant}population {Ans: A group of individuals of the same species that occupy the same environment and can interbreed with one another.}Genetic drift {Ans: A change in genetic variation from generation to generation due to random chance. (Fitness has no effect).}allele frequency {Ans: # of copies of an allele/total # of alleles in population}bottleneck effect {Ans: A change in allele frequencies due to genetic drift in a population that has been dramatically reduced in size; this effect can reduce the genetic diversity of the population (natural disaster, hunting, habitat loss)}mutant allele {Ans: An allele that has been altered by mutation.}
