4. In a given population, 16% of the population has blue eyes and 84% has brown eyes. Although eye color is a polygenic trait, let us assume for this problem that the brown-eyed allele is dominant to the blue-eyed allele and that the population is in Hardy-Weinberg equilibrium. What are the gene frequencies for brown eyed and blue-eyed alleles? = '16 Pa Brown-eyed allele frequency: _ qe 0.4 Pa 0.4 Blue-eyed allele frequency: - In this same population, there are...
