Question

Assertion (A): Genetic maps are extensively used as a starting point in the Human genome sequencing project.
Reason (R): Frequency of recombination between gene pairs on the same chromosome as the measure of distance between genes and mapped their position is called gene mapping.

• (A) and (R) are true. (R) is correct explanation for (A)
• (A) and (R) are true. But (R) is not correct explanation for (A)
• (A) is true, but (R) is false
• (A) is false, but (R) is true

Hint:

Gene mapping = estimating gene position via crossover frequencies — foundational in genomics.

Answer 1

The Correct Option is A

Both statements are true — gene maps based on recombination frequencies were used to determine gene positions and initiate sequencing.
Hence, (R) correctly explains (A).
