The allelic frequency of the red fur gene is changed from twenty to thirty percent due to the presence of new genes by evolution.
Further Explanation:
Alleles are the variants of the gene. They contain genetic information in the gene. Allele frequency is defined as the total number of incidence of an allele in a population. Allele frequency help in explaining the diversity of species in a population. It can be calculated or measured by dividing the total number of times that particular interest of allele is noticed in a gene pool by the total number of copies of that allele. The percentage, fraction and decimal can represent it.
The allelic frequency mainly reflects the genetic diversity in a population. Change in the allelic frequency in a population mainly specifies that new mutations or changes have occurred. Change in allelic frequency occurs due to:
- Mutations
- Natural selection
- Gene flow
- Genetic drift
Therefore, change in the allele frequency of the red fur gene in a fox gene pool indicates that the population of the fox is evolved.
