- AMorgan hybridised yellow-bodied, white-eyed females to brown-bodied, red-eyed males and intercrossed their F 1
- BMorgan observed that the two genes segregated independently of each other and the F 2 ratio did not deviate fr
- CMorgan attributed this to the physical association or linkage of the two genes and coined the term linkage to
- DMorgan and his group also found that even when genes were grouped on the same chromosome, some genes were very
Correct answer
B. Morgan observed that the two genes segregated independently of each other and the F 2 ratio did not deviate fr
Step-by-step solution
Morgan carried out several dihybrid crosses in Drosophila to study genes that were sex-linked. The crosses were similar to the dihybrid crosses carried out by Mendel in peas. For example Morgan hybridised yellow-bodied, white-eyed females to brown-bodied, red-eyed males and intercrossed their F 1 progeny. He observed that the two genes did not segregate independently of each other and the F 2 ratio deviated very significantly from the 9:3:3:1 ratio (expected when the two genes are independent). Morgan and his group
