Question

Factors not observed in parent generation can be observed in F2 generation. explain the statement by showing the possible progenies when a tall plant with round seeds is crossed with dwarf plant with wrinkled seeds using a punnett square.​

Answer 1

Answer:

Explanation:

A cross is made between homozygous yellow round seeds(YYRR) to another homozygous green wrinkled seeds(yyrr). In the F1 generation, all plants are heterozygous yellow round(YyrRr). When this plant is subjected to self pollination, in the F2 generation, 9 plants are Yellow round, 3 plants are yellow wrinkled, 3 plants are green round and 1 plant is green wrinkled are formed.

The dihybrid phenotypic ratio is 9:3:3:1.

So, the correct option is ‘9:3:3:1’.
