Question:
In horses, the genes for white coat color and red coat color are codominant. Heterozygotes have a light red coloration, called roan.
If you located a population of wild mustangs in a valley that had 476 red horses, 323 roan horses, and 51 white horses, could you say the population is in Hardy Weinberg equilibrium?
First calculate p and q, then use the Hardy-Weinberg formula to calculate expected genotypic frequencies.
