Detailed explanation-1: -Since capital R = round and is dominant that means that RR and Rr will all be round seeds. That means that ¾ or 75% of the offspring produced will be round. Since, wrinkled is rr, then ¼ or 25% of the offspring will be wrinkled. The genotype is the gene make-up of the offspring.
Detailed explanation-2: -Hence, we see that the ratio of round seed: wrinkled seed is 3:1. i.e, 3/4 or 75% of all offsprings resulting from this cross will be produce round seeds.
Detailed explanation-3: -In the F1 generation, 50% of the offspring produced wrinkled seeds.
Detailed explanation-4: -In peas, round seed shape (R) is dominant to wrinkled seed shape (r), and yellow seed color (Y) is dominant to green seed color (y). A pea plant which is homozygous round seed and has green seed color is crossed with a pea plant that is heterozygous round seed shape and heterozygous yellow seed color.
