Principles of Inheritance and Variation

Solution:

• Morgan carried out several dihybrid crosses in Drosophila to study genes that were sex-linked
• Morgan attributed that proportion of parental gene combination is more than the non-parental type due to the physical association
• Alfred Sturtevant used the frequency of recombination between gene pairs on the same chromosome and find genetic map.
