Principle of Inheritance and VariationHard
Question
Lack of independent assortment of two genes A and B in fruit fly Drosophila is due to
Options
A.repulsion
B.recombination
C.linkage
D.crossin over
Solution
W Bateson (1905) explained the Iack of Independent assortment in sweet pea and T H Morgan (1905) in Drosophila due to linkage. When genes closely present adhere or link together in a group and transmitted as a single unit, the phenomenon is called linkage. It stops the process of independent assortment. Incomplete linkage is broken down due to the crossing over.
