Exercise 61

What are the expected phenotypic ratios from the following cross: Tt Rr yy Aa × Tt rr YY Aa , where T = tall, t = dwarf, R = round, r = wrinkled, Y = yellow, y = green, A = axial, a = terminal; T , R , Y , and A are dominant alleles. Note: See solved problem S3 for help in answering this problem.Solved Problem S3
A pea plant is heterozygous for three genes ( Tt Rr Yy ), where T = tall, t = dwarf, R = round seeds, r = wrinkled seeds, Y = yellow seeds, and y = green seeds. If this plant is self-fertilized, what are the predicted phenotypes of the offspring, and what fraction of the offspring will occur in each category
