The vestigial gene, with a dominant vg ^+ + allele that specifies normal, long wings and a recessive vg allele … WebSolution. Complete linkage is exhibited when the genes for a particular character are present very close to one another. It is.due to non-break in the gene combination situated on a chromosome. On the other hand, incomplete linkage occurs when the genes for different characters are separated at the time of gamete formation due to breaking and ...
WebIncomplete linkage 1. Genes present in the same chromosome have a tendency to separate due to crossing over and hence produce recombinant progeny besides the parental type. 2. The number of recombinant individuals is usually less than the number expected in independent assortment.
