Q18 of 61 Page 1

Mendel in one of his experiments with pea plants crossed a variety having round seeds with one having wrinkled seeds. Write his observations, giving reasons, of F1 and F2 progeny.

Mendel crossbred round seed plants with wrinkled seed plants, it was observed that in F1 progeny, only round seed plants were obtained and no wrinkled seed plant was obtained. But in F2 generation, both round and wrinkled seed plants were obtained in 3:1 ratio. Since, in F1 progeny, only round seeds were obtained so, dominant trait was round seed and recessive trait was wrinkled seeds.
