Read the following statements.
(i) Morgan carried out several monohybrid crosses in Drosophila to study genes that were sex-linked.
(ii) Morgan attributed that proportion of parental gene combination is less than the non-parental type due to the physical association.
(iii) Term recombination was coined by Morgan to describe the generation of non-parental gene combinations.
(iv) Alfred Strutevent used the frequency of linkage between gene pairs on the same chromosome and find genetic map.
Select how many are incorrect statement(s).

Options

A. 3
B. 1
C. 4
D. 2

Answer

A

Explanation

• 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.
