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 now 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: -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-2: -Allele frequency refers to how common an allele is in a population. It is determined by counting how many times the allele appears in the population then dividing by the total number of copies of the gene.

Detailed explanation-3: -temporal isolation, in biology, a type of reproductive isolation mechanism among sexual organisms in which the differences in the timing of critical reproductive events prevent members of closely related species, which could otherwise breed with one another, from mating and producing hybrid offspring.

Detailed explanation-4: -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.
