Two genes R and Y are located very close...

Two genes R and Y are located very close on the chromosomal linkage map of maize plant. When RRYY and rryy genotypes are hybridized the `F_(2)` segregation will show

A

Higher number of the recombinant types

B

Segregation in the expected 9 : 3 : 3 : 1 ratio

C

Segregation in 3 : 1 ratio

D

Higher number of the parental types

Text Solution

Verified by Experts

The correct Answer is:
D
Since both R and Y genes are very close on the chromosomal linkage map they do not segregate independently as a result chances of recombination are very less thus `F_2` segregation will show higher number of parental types.
