R and y genes of Maize lie very close to each other . When RRYY and rryy gneotypes are hybridised , `F_(2)` genertion will show

A

Segregation in `9.3:3:1`

B

Segregation in `3:1` ratio

C

Higher number of parental types

D

Higher number of recombinant types

Text Solution

Verified by Experts

The correct Answer is:
C
R and Y genes of Maize lie very close to each other. When RRYY and rryy genotypes are hybridised, `F_(2)` generation will show higher number of parental types due to linkage.
