Mendel law of independent assortment does not hold true for the genes that are located closely on

Options

A. same chromosome
B. non-homologous chromosomes
C. X-chromosome
D. autosomes

Answer

A

Explanation

As per linkage experiments carried out by Morgan, the two linked genes do not always segregate independently of each other and `F_(2)` ratio deviated very significantly from `9:3:3:` ratio (expected when two genes are independent). Hence, if linkage was known at the time of Mendel, he would not have been able to explain law ofd independent assorment.
