Detailed explanation-1: -In the F1 generation, 50% of the offspring produced wrinkled seeds.
Detailed explanation-2: -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-3: -So here in discussion. In first part, when a pure breed round seed is crossed with power breed wrinkled seeds, which means for pure pre round seed, the genotype will be capital R, capital R. And pure breed wrinkle C genotype will be smaller and smaller. Which is homosexuals recessive and they’re paired with around.
Detailed explanation-4: -In a homozygous plant round seeds (R) are dominant over wrinkled seeds (r). (i)Draw a Punnett square to show the gametes and offspring when both the plants have heterozygous round seeds (Rr). (ii) Mention the phenotype and genotype ratios of the offsprings in F2 generation.
