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.

¿Cómo se le llama a los que pudieron dar origen a los seres vivos actuales?
natta225 [31]

Answer:

Una de las características de los seres vivos se encuentra en su composición biológica, dado que todos ellos están constituidos por cuatro bioelementos esenciales que se encuentran de manera abundante en la naturaleza:

Carbono

Hidrógeno

Oxígeno

Nitrógeno

Estos bioelementos o elementos biogénicos están presentes en las biomoléculas, que son las que dan forma a la materia que constituye a los seres vivos. Estas moléculas están formadas, a su vez, por la unión de átomos.

De estos bioelementos, es importante destacar el papel del hidrógeno y el oxígeno, que dan lugar a la molécula del agua. El agua, o H2O, juega un papel fundamental en el funcionamiento de los seres vivos.
