During deer season in Kansas, one county reported a harvest of 657 white-tailed

Question

During deer season in Kansas, one county reported a harvest of 657 white-tailed deer. Also, a researcher was interested in knowing the prevalence of albinism in the county’s population, so all hunters who reported deer kills in that county also were asked to report whether or not they killed an albino deer. Although the sample of albino deer killed might have been somewhat biased (i.e., because hunters might more likely shoot an albino for various reasons), let’s assume the 3 deer reported killed as albinos in the county was a representative sample of albinos in the population at-large. How many of the 657 deer killed in that county would have been predicted to have had normal coloration, but being heterozygous would have carried a recessive allele for albinism?
