Answer #1

The correct answer is C. RANDOMLY:INCREASE.

Mutations arise randomly across the genome and increase the molecular diversity of a population.

Mutations increase the genetic diversity in the gene pool of the population. Thus the molecular diversity of the population also increases considerably. During mutation new type of genes are introduced to the gene pool else existing genes are altered to new one. Thus genetic variation is obtained any how duting mutations.

Mutation is a random process because it is a random error that occurs during replication. Thus the error produce different allele that give rise to different genes products.

Thank you. Please do provide with a Thumbs up.
