From a cross Aa BB`xx`aa BB, following genotypic ratio will be obtained in `F_(1)` generation

A

1 Aa BB : 1 aa BB

B

1 Aa BB : 3 aa BB

C

3 Aa BB : 1 aa BB

D

All Aa BB : No aa BB

Text Solution

Verified by Experts

The correct Answer is:
A
(a) `AaBBxxaaBB`
Gametes for `F_(1)`=AB,aB and aB, aB
After crossing =AaBB,aaBB
Ratio= 1:1
