Question

The process when some species migrate from the original to a new place, which in turn changes the allele frequency is called ______

(a) Gene drift

(b) Gene migration

(c) Gene travel

(d) Genetic recombination

I got this question during an interview.

The doubt is from Hardy-Weinberg Principle-2 topic in division Evolution of Biology – Class 12

Answer 1

Correct answer is (b) Gene migration

For explanation I would say: Gene migration or gene flow occurs when some species migrate from original to a new place. This changes the allele frequency in the old as well as a new place. So, new genes or alleles are being added to the new population and removed from the old one.
