Horns
Poll
In beef cattle of European ancestry, the trait of having horns or being polled (no horns) is determined
by a single locus with two alleles (H and h). The polled (no horns) allele (H) is dominant to the horned
allele (h).
There is a very big cattle ranch with 10,000 cows and bulls. With all those cattle it is hard to keep
track which cow mates with which bull, so their mating is random. That same ranch does not like
to breed their cattle with cattle from other ranches, since they have the "best cattle in Uruguay".
Assume H-W equilibrium since there are no evolutionary forces and mating is random.
There are 2,056 polled cattle. How many of the polled cattle are homozygotes? (Your answer should
be the "number of individual cattle", not the frequency.
