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 ) Segregation in the expected 9 : 3 : 3 : 1 ratio
( B ) Higher number of the parental types
( C ) Higher number of the recombinant types
( D ) Segregation in 3 : 1 ratio
