Question

A population of lizards lives on Island A. On nearby Island B, another population of the same species is present. The lizards on Island A have evolved to have a large frill around their necks. The lizards on Island B, on the other hand, have evolved to have a much smaller neck frill.

Both islands are colonized by humans and some of the lizards on Island A are transferred to Island B. The lizards from Island A interbreed with the lizards on Island B. The gene coding for the large neck frill is passed on to the offspring resulting from these breedings, introducing new genetic variation into the population.

The transfer of genetic information that occurs between the two lizard populations above is known as

Answer 1

The transfer of genetic information that occurs between the two lizard populations is known as GENE FLOW.

Step-by-step explanation:

The options attached to this question are given below:

A. Genetic recombination.

B. Gene flow.

C. Genetic drift.

D. Natural selection.

Gene flow refers to the transfer of genetic variations from one population to another of the same species. The rate of gene flow between two populations may be low or high. When the rate of gene flow is high the populations are considered to be a single population.

In the scenario given in this question, there is a flow of large neck frill genetic trait from the parent lizards in Island B to the offspring that result from sexual relationship between the lizards from both islands.
