EVOLUTION OF A POPULATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following cannot introduce new alleles into a population’s gene pool?
A
Mutation
B
Natural selection
C
Gene Flow
D
All of the above introduce new alleles into the population
Explanation: 

Detailed explanation-1: -natural selection is incorrect as it is the process with the help of which species adapt to the new environment by changing the genetic makeup. It does not introduce new alleles into the population.

Detailed explanation-2: -Gene flow can cause new alleles to enter a population’s gene pool.

Detailed explanation-3: -Natural selection works by selecting for alleles that confer beneficial traits or behaviors, while selecting against those for deleterious qualities. Mutations introduce new alleles into a population.

Detailed explanation-4: -The composition of a population’s gene pool can change over time through evolution. This can occur by a variety of mechanisms, including mutations, natural selection, and genetic drift. The result is a gene pool that is altered to be attuned to the needs of the population’s specific environment.
