Question
Please explain.
Use the information below to answer the next three questions: In a species of tree, seed color is determined by four independently assorting genes: A, B, C, D. The recessive alleles of each of these genes produce abnormal enzymes that cannot catalyze a reaction in the biosynthetic pathway for seed pigment. This pathway is diagrammed as follows: red White yellow Orange precursor blue When both red and blue pigments are present, the seeds are purple. Trees with the genotypes AaBbCcDd and AaBbCcdd were crossed. 34.What was the color of the seeds from which the two parents whose genotypes are given above derived from? A. red and white B. blue and white C. purple and red D. blue and purple E. orange and purpleExplanation / Answer
34) purple*red
35) proportion white-- 1/4
36) proportion red-- 27/128
proportion white-- 32/128
proportion blue-- 9/128
