NEET 2004 Biology question

Lack of independent assortment of two genes A and B in fruit fly Drosophila is due to :-

(1)Recombination
(2)LinkageCorrect
(3)Crossing over
(4)Repulsion

Answer: (2)

Solution

Genes located close together on the same chromosome tend to be inherited together and therefore do not assort independently; this physical association of genes on a chromosome is called linkage (Morgan's work on Drosophila). Recombination and crossing over break linkages and produce new
