#19. In cattle, the polled, or hornless, trait (P) is dominant over the horned trait (p).
In an ideal cattle population exhibiting Hardy–Weinberg equilibrium, 23 out of every 125 calves are horned. Calculate the frequency of the recessive allele in the population.
Express your answer using two significant digits.
#20.There is a lack of dominance in black (B) and white (W) horse coat colours. An offspring produced from a black horse and a white horse has a blue-roan coat colour (BW). When the blue-roan coat is closely examined, both black and white hair can be found.
In an ideal horse population exhibiting Hardy–Weinberg equilibrium, 10 out of every 150 foals have a white coat. Calculate the frequency of the black horse coat allele in the population.
