Vedclass · Answer

(D) The law of independent assortment is not applicable when genes for different characters are located on the same homologous chromosome,i.e.,linked genes.Since genes $R$ and $Y$ are located very close to each other,they exhibit strong linkage.Strong linkage results in a very low frequency of crossing over between the genes.Consequently,the offspring will show a significantly higher number of parental types compared to recombinant types in the $F_{2}$ generation.

Two genes $R$ and $Y$ are located very close on the chromosomal linkage map of maize plant. When $RRYY$ and $rryy$ genotypes are hybridized,then $F_{2}$-segregation will show
