Vedclass · Answer

(A) : If in a dihybrid test cross,more parental combinations appear compared to the recombinants in the $F_2$ generation,it is indicative of the involvement of linkage.Linkage is the tendency of two different genes on the same chromosome to remain together during the separation of homologous chromosomes at meiosis.During complete linkage,no recombinants are formed,whereas in incomplete linkage,a few recombinants are produced along with parental combinations.

In a test cross involving $F_1$ dihybrid flies,more parental-type offspring were produced than the recombinant-type offspring. This indicates
