Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

An earthquake causes an ocean channel to open up on an island where a low area previously existed. The island’s lizard population is not separated on the two parts of the island, providing an example of

A	geographic isolation
B	behavioral isolation
C	disruptive selection
D	temporal isolation

Explanation:

Detailed explanation-1: -Behavioral Barriers:-is isolation caused by differences in courtship or mating behaviors. Geographic Barriers:-involves physical barriers that divide a population into 2 or more groups.

Detailed explanation-2: -Animals experience gene flow when individuals leave a family group or herd to join other populations. The flow of individuals in and out of a population introduces new alleles and increases genetic variation within that population.

Detailed explanation-3: -Answer and Explanation: The only choice that would favour intermediate phenotypes of a species over extreme phenotypes within a particular population is stabilizing selection. Stabilizing selection will select against extreme phenotypes of a particular species.

Detailed explanation-4: -Allele frequency (also called gene frequency) is the term used to describe the fraction of gene copies that are of a particular allele in a defined population.
