Question 2: In vampires, the widow's peak hairline is caused by recessive trait coded for by a gene on the X-chromosome. In vampires, females are homozygous in their sex chromosome, while males are the heterogametic sex. If a female carrier for the widow's peak phenotype mates with a normal male, what is the probability that any boy offspring will have a widow's peak? will she increase her chances of having a boy with a widows peak by finding a mate with a widow's peak?
