Hardy Weinberg equilibrium model generated
expectations.
4.1 In a species of bird, feather color is controlled by
genes at a single locus, with the red feather allele dominant to
the yellow feather allele. A population has 22 red and 14 yellow
birds, with 9 of the red birds having a homozygous dominant
genotype. Is this population in equilibrium?
Calculate p and q from the number of individuals of each
genotype:...
