Newton was a great scientist who gave the world "The Law of Gravitation", which means that in the universe every particle is attracting other particle and the force with which it attracts is directly proportional to the object of their mass and inversely proportional to the square of the remoteness in between their centers.

Although selection operates against deleterious alleles in populations, they are rarely lost from these populations. For example
KonstantinChe [14]

Answer:

Deleterious alleles appear sporadically in a population

Explanation:

A population with a deleterious allele will have no or few individuals that have the ability to pass along these traits. These alleles appear less in a population because of selective pressure but they are not always absent. The alleles appear less often but are are not always passed on and the others that are genetically fit are able to pass along their genes. The reason the population equilibrium is not zero is because these alleles do appear but they are not necessarily passed along. These individuals may not be able to reproduce or reach the age of reproduction.

Deleterious alleles appear more often, making individuals less fit genetically, i.e. they pass fewer copies of their genes to future generations. Put another way, natural selection purges the deleterious alleles.
