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 showA. higher number of the recombinant typesB. segregation in the expected 9 : 3 : 3 : 1 ratioC. segregation in 3 : 1 ratioD. higher number of the parental types

Answer» Correct Answer - D
Higher number of the parental types formed when RRYY and rryy genotypes are hybridised giving the condition that R and Y genes are closely linked. Law of independent assortment does not applicable when the gene of different character occupy the same homologous chromosome i.e. are linked gene.
