Detailed Solution

The two genes did not segregate independently and the F₂ ratio deviated from 9 : 3 : 3 : 1 ratio in Morgan experiments on Drosophila. Genes that Morgan studies were located on X chromosome. When two genes are situated on same chromosome, the proportion of parental gene combination is much higher than non parental type due to linkage.
