Vedclass · Answer

(C) In a dihybrid cross,if genes are located on the same chromosome and are close to each other,they tend to be inherited together,a phenomenon known as $Linkage$.Because of $Linkage$,the parental gene combinations are maintained in the progeny at a higher frequency than the recombinant (non-parental) combinations.Independent assortment,as proposed by Mendel,would result in a $1:1:1:1$ ratio of parental and recombinant types,but $Linkage$ deviates from this,leading to a higher proportion of parental types.

In the progeny of a dihybrid cross,the frequency of parental combinations is higher than that of non-parental combinations. This is due to:
