Assertion : Heterochromatin is genetically inactive.
Reason. : It lacks genes.

Options

A. If both the assertion and the reason are true and the reasons is a correct explanation of the assertion
B. If both the assertion and reason are true but the reason is not a correct explanation of the assertion
C. If the assertion is true but the reson is false
D. If both the assertion and reason are false

Answer

C

Explanation

Genetic analyses indicate that heterochromatin is largely genetically inactive. Most of the genes of eukaryotes that have been extensively characterized are located in euchromatic region of the chromosomes. The earlier belief that no genes are found in heterochromatic regions is not correct , because genes could be located in heterochromatic region in several cases like Drosophila and tomato. the genes in heterochromatic region perhaps become active for a short period.
