Principles Of Inheritance And Variation

Question

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

  • repulsion

  • linkage

  • crossing-over

  • recombination

Solution

B.

linkage

Mendel's law of independent assortment always fails where linkage is found i.e., lack of independent assortment of genes A and B in fruit fly Drosophila melanogaster is due to linkage.

This is mainly because when two traits were found not to assort completely independently. Linked genes do not independently assort. They are located on the same chromosome and that tend to be inherited together.
