WebMay 14, 2024 · If two individuals mate that are heterozygous (e.g., Bb) for a trait, we find that 25% of their offspring are homozygous for the dominant allele ( BB) 50% are heterozygous like their parents ( Bb) 25% are homozygous for the recessive allele ( bb) and thus, unlike their parents, express the recessive phenotype. WebYes Hardy-Weinberg is mainly used to calculate the expected frequency assuming: no mutations, no gene transfer, random mating, large population, and no selection. However if we know the actual frequency of the homozygotes (i.e. p^2 and q^2) in the actual population we can compare to an expected value. So p+q should = 1 , in a real population if ... city california pass
