Question

Mendel also carried out experiments to observe inheritance of two pairs of contrasting characters.
which is called dihybrid cross. He cross breed pea plants bearing round green seed with plants
bearing wrinkled and yellow seeds. In the Fl generation he obtained all round and yellow seeds it
means round and yellow trails of seeds are dominant features while wrinkled and green are recessive
He seli-pollinated the plants of Fl generation to obtain F2 generation, he obtained four different
types of seeds round yellow, round green, wrinkled yellow and wrinkled groen in the ratio of
9 :3:3:1 He concluded that traits are independently inhented
The expected phenotypic ratio obtained by crossing the Fl generation in dihybrid cross would be
a)3:1
b) 1:2:1
c) 9:3:3:1
d) 1:2:1:2:4:2:1 :2:1​

Answer 1

Answer:

Option (c)

Explanation:

The expected phenotypic ratio obtained by crossing the F1 generation in dihybrid cross would be? Explanation: The phenotypic ratio obtained by the dihybrid cross is 9:3:3:1 while that by a monohybrid cross is 3:1.
