When Mendel crossed yellow- seeded and green- seeded pea plants, all the offspring were yellow seeded. When he took these F₁yellow- seeded plants and crossed them to green- seeded plants, what genotypic ratio is expected?

Question

Quizplus · Accepted Answer

In this cross, the yellow-seeded plants from the F1 generation are heterozygous (Yy) and the green-seeded plants are homozygous recessive (yy). When crossed (Yy x yy), the expected genotypic ratio is 1:1, with half the offspring being heterozygous (Yy) and half being homozygous recessive (yy).
