Solution
The correct option is C Assertion is correct but Reason is incorrect
It is true that chromosomes occur in pairs. These are called homologous chromosomes. They contain genes that are located on homologous sites.
During the process of meiosis, these chromosomes get segregated and get independently assorted.
But the alleles that are not located on nonhomologous chromosomes, they are present only on homologous chromosomes.
