To reach the Hardy-Weinberg equilibrium, what must a population do? have no changes in allele frequency.

migrate to another geographical area.

reproduce sexually with another population.

have a beneficial mutation introduced into the population.

Answer is A

Explanation:

Hardy-Weinbergs equilibrium is laso referred as genetic equilibrim i.e. gene pool's frequency is not changing. Now why not other choices

if the population migrate to another geographical area so ofcourse it would have people with different genes

if that population sexually reproduce with another population it would have You know AGAIN different genes

Mutation is the change in DNA so if there is change in DNA the genetic message by the gene would not be the same as before the mutation so it also affects genetic equilibrium.

WHAT AFFECTS GENETIC EQUILIBRIUM

The Factors which affect genetic equilibrium are Mutation, Environmental Change, Natural Selection

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
