11. Choose from the following types of inheritance and write in the 1st column which one is described by each situation: (1) 2 linked genes (2) polygenic (3) Multiple alleles (4) Incomplete dominance (5) dihybrid cross. Type of Inheritance Description In the F2 generation of a certain plant, % have no thorns, % have long thorns, and % have short thorns. In another set of plants, also an F2 generation, you find the following phenotype ratios: 9 red flowers with broad leaves, 3 red flowers with narrow leaves, 3 white flowers with broad leaves, and 1 white flower with narrow leaves. In a certain species of bird, you see some birds with barely any crest on their head, some with very long crests, and many birds with crests of all possible lengths in between. In a certain species of insect, three eye colors are known: red, orange, and yellow. If purebred red-eyed individuals are crossed with purebred orange-eyed, all the offspring are red-eyed. If purebred orange-eyed are crossed with purebred yellow-eyed, all the offspring are orange-eyed. If purebred red-eyed are crossed with purebred yellow-eyed, all the offspring are red-eyed. In another case in which you study 2 traits of a plant at the same time, you find in the F2 generation that % have hairy stems and green seeds while the other % have smooth stems and brown seeds.
