Back Restart

When large population is drastically reduced by a disaster and then recovers changing allele frequencies

bottleneck effect

when there is a double set of chromosomes to preserve alleles

diploidy

what is hardy weinberg equation for genotypes?

p2 + 2pq + q2 = 1

3 conditions for Hardy weinberg equilibrium to be true

no natural selection, no mutations, no gene flow, random mating, large population

Within a population of butterflies, color brown (B) is dominant to color white (b). 40% of all butterflies are white. Calculate the frequency of the recessive allele
