Question

Loss of habitat has decreased the population and number of alleles of Canadian lynx. A few survivors migrated to other forests and multiplied, but there is less genetic variation in the offspring. Which statement is true about this event?
A) Genetic drift occurred in the population of Canadian lynx resulting in a founder effect later on.

B) Gene flow occurred in the population of Canadian lynx. Then genetic drift occurred.

C) The population of Canadian lynx experienced a founder effect. Later, genetic drift occurred.

Answer 1

Answer:

The correct answer would be option A.

Genetic drift is one of the natural phenomenons which caused evolution.

It changes the frequency of an allele in a population.

The effect of genetic drift is maximum in small populations or when population size gets reduced to very small due to factors such as overhunting, loss of habitat, natural calamity et cetera.

Similarly, genetic drift occurs in a population of Canadian lynx as population size and thus, allelic frequency is reduced due to loss of habitat.

Later, when few survivors migrated to other forests, they would act as the founder population for upcoming generations.

Thus, the founder effect would occur later on.

Answer 2

The Correct Answer is A
Reasoning - Since the ani. had went into a different ecosystem and habitat amd mateded it had offspring with the originally some genetic along with some little different variations. In turn this is call Founders Effect
