Question
  1. Following up on Question 6, assuming random mating, what would be the percentage of long-horned baby Minotaur who are heterozygous at the H locus?

      A.

    23.5%

      B.

    25.0%

      C.

    50.0%

      D.

    51.5%

      E.

    68.0%

Minotaur is only found in the Labyrinth on the island of Crete. The area is famous for its annual spectacle of “Minotaur run,” where herds of Minotaur rush out of the Labyrinth to reach their breeding grounds on the beautiful Aegean seashore. A group of Olympian scientists discovered that the horn size of the Minotaur is controlled by a single locus H. A previous population genetic survey showed that there are only two alleles in this locus, H1 and H2. Furthermore, it was found that the H2 allele is recessive. Several studies showed that the long-horned individuals (H1H1 and H1H2) tend to be tangled up along the way during the annual migration out of the Labyrinth, such that only 80% of the long-horned individuals can make it out of the Labyrinth alive. Once outside the Labyrinth, the short-horned individuals tend to be less successful at finding food, thus 60% would die from starvation before the beginning of the breeding season. Initially, the annual migration of Minotaur started out with 1,000 individuals (150 H1H1, 500 H1H2, and 350 H2H2) inside the Labyrinth.
