Answer 2

Answer:

monohybrid cross between two pure breeding varieties (round, RR and wrinkled rr seeds) obtains all progeny with round seeds (Rr) in F

1

generation. Selfing of F

1

hybrids obtains progeny with round and wrinkled seeds in 3: 1 ratio respectively. It shows the law of dominance allowed only dominant factor (round seed) to be expressed in F

1

hybrid, although it inherited the recessive trait (wrinkled seed) from parents which was then expressed in F
