Question

In pea plants, the round seed is dominant over the wrinkled. If across is carried out between these two plants, answer the following questions: (a)Mention the genes for the trait of a parent. (b)State the trait of the F1 hybrid. (c)Write the phenotypic and genotypic ratio of F2 progeny obtained from this cross? What is the name of the cross?

Answer 1

Answer:

In pea plant form of seed is of two types: Round(R) which is a dominant trait and Wrinkled(r) which is a recessive trait. In F

1

generation, Mendel cross-pollinated a pure round pea( RR) and a pure wrinkled pea(rr). He called them parental generation. He collected the seeds produced by this cross and grew plants from them. All these plants were found to be round.

The F

1

plants were pollinated among themselves called selfing. The F

2

plants were found to contain both round and wrinkled individual. They were in the ration of three round and one wrinkle.

So, the genes for the traits of parents are pure round(RR) and pure wrinkled(rr).
