What is one condition that must be met for a population to be in genetic equilibrium? A. There is nonrandom mating. B. There is
Ksenya-84 [330]

Answer:

C. There is no genetic drift

Explanation:

A population is said to be in genetic equilibrium when the genetic variation of a population remains constant over many generations.

For a population to remain in genetic equilibrium it is necessary that external factors that disturb the equilibrium should not be present.

The external factors that are responsible for disturbing the genetic equilibrium are mutations, non-random mating, genetic drift and gene flow.

Genetic drift occurs when due to a chance event the allele frequency of a population either increases or decreases and this is usually common in small populations.

Thus, genetic drift should not occur so that the population can be in genetic equilibrium.

Mia conducted a five hour experiment. She used a liquid solution. The solution decreased by 9/8 ounces every hour for 5 hours. A
sasho [114]

Given:

The solution decreased by \dfrac{9}{8} ounces every hour for 5 hours.

Remaining solution at the end of the experiment = \dfrac{99}{8} ounces.

To find:

The initial amount of solution.

Solution:

Let the initial amount of the solution be x.

The solution decreased by \dfrac{9}{8} ounces every hour for 5 hours.

Total decreased amount  =\dfrac{9}{8}\times 5

                                          =\dfrac{45}{8}

Initial amount = Remining amount + Decreased amount of solution.

x=\dfrac{99}{8}+\dfrac{45}{8}

x=\dfrac{99+45}{8}

x=\dfrac{144}{8}

x=18

Therefore, the initial amount of solution is 18 ounces.
