Question

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 is expected in 9: 3:3:1 rate
C. Secgregation in 3:1 ratio
D. Higher number of parental types

Answer 1

Correct Answer - D
F2- segregation will whow higher number of parental types. When two genes are linked than the recombinantion frequency is less and there is higher number of parental types.
