Unformatted text preview: 2 (2 points) : Recall that female squirrel monkeys are trichromatic if they have both a red and green allele on their two X-chromosomes. Suppose the frequency of a red X is 0.4 and a green X is 0.6. What is the fraction of green-only females? . 6 . 6 = 0 . 36 Red-only females? . 4 . 4 = 0 . 16 Trichromatic females? 2 . 4 . 6 = 0 . 48 3 (5 points) : Plant species A has diploid chromosome number 2n = 10, species B has diploid number 2n = 20, and species C has number 2n = 30. What is the chromsome number for (a) An autotetraploid for species A ? 20 (b) An allotetraploid involving A and C? 40 (c) A gamete from an autotetraploid from species C? 30 (d) A trisomic individual from species C? 31 (e) A nullisomic individual from species A? 8 1...
