R and y genes of Maize lie very close to...

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

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
(d) When two genes are located very closely on chromosome they are called as "Linked genes" and they inherit together therefore two types of gametes will be formed in maximum numbers. Thus higher number of the parental type off springs will be seen in `F_(2)` generation.
