Question

When Morgan conducted dihybrid cross on Drosophila like Mendel did with pea plants, the ratios deviated significantly from that of Mendel’s F2 ratio. Write the explanation Morgan and his group gave to the observations they obtained from their experiment.

Answer 1

-When two genes in a dihybrid cross were located on the same chromosome they did not segregate independently
- The proportion of parental gene combinations were much higher than non parental combinations / recombinants 
- Physical association of two genes was termed linkage
