You are studying a population of sparrows in which phenotype is determined by a single locus. Only two alleles for that locus are known for this population which are distinguished by the codes 'A' and 'a'. Distribution of phenotypes in the population indicates that 49% of the population is 'AA' homozygous, 42% are heterozygous, and 9% 'aa' homozygous. How do you determine the allele frequency for 'A' and 'a' based on these observations?

Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offspring. a parakeet that is heterozygous for blue feathers (dominant) is crossed with a parakeet that is homozygous for white feathers (recessive). according to the punnett square for this cross, what percentage of offspring is predicted to have blue feathers? 25 percent 50 percent 75 percent 100 percent
