Vedclass · Answer

(B) In a dihybrid test cross $(AaBb 	imes aabb)$,if the genes are completely linked,only $2$ types of offspring are produced (parental types).However,with incomplete linkage,crossing over occurs between the linked genes.This results in the formation of $4$ types of gametes: $2$ parental types and $2$ recombinant types.Therefore,when these gametes are crossed with the tester $(aabb)$,$4$ distinct phenotypic and genotypic classes of offspring are produced.

In a test cross of a dihybrid plant with incomplete linkage,how many types of plants will be produced?
