Extracted text: Guide Questions 1. Examination of thousands of plants in a certain species revealed a range of pubescence from 60 hairs/cm to the glabrous (non-pubescent) condition. Assume that this variability is controlled by three gene pairs having a cumulative effect. Ignore the environment effect. When entirely pubescent (60 hairs/cm) were crossed to glabrous plants (0 hairs/em), all offsprings in the F, exhibited an intermediate pubescent condition (30 hairs/cm). Several of the Fi plants were selfed and the F2 plants were evaluated for pubescence. a. Assign genotypes to the original plants and the Fi plants. b. What proportion of the F2 progeny would be expected to be: i. Completely pubescent (60 hairs/cm)? Intermediate pubescent (30 hairs/cm*)? With 40 hairs/cm?? Homozygous for the genes involved? ii. iv.
