Vedclass · Answer

(D) When two genes are located very close to each other on the same chromosome,they exhibit the phenomenon of linkage. Linkage refers to the physical association of genes on a chromosome,which results in the tendency of these genes to be inherited together. Because the genes $R$ and $y$ are closely linked,the frequency of crossing over between them is very low. Consequently,the gametes produced will predominantly be of the parental type ($RY$ and $ry$). In the $F_2$ generation,this results in a significantly higher proportion of offspring showing parental phenotypes compared to recombinant phenotypes,deviating from the independent assortment ratio of $9:3:3:1$.

In maize plants,genes $R$ and $y$ are located very close to each other on the chromosome map. When a cross is made between $RRYY$ and $rryy$ genotypes,what will the $F_2$ analysis show?
