Question

What is the term for an allele being increased in frequency until it is the only allele present in the population (i.e. it replaces all other alternative alleles)?

A. Genetic drift
B. Allelic variation
C. Allelic fixation
D. Heterozygosity

Answer 1

Allelic fixation is the term for an allele being increased in frequency until it is the only allele present in the population. It can occur through natural selection, genetic drift, or the founder effect.

Step-by-step explanation:

An allele being increased in frequency until it is the only allele present in the population is known as allelic fixation. It occurs when one allele becomes so prevalent that it replaces all other alternative alleles. This process can happen through natural selection, genetic drift, or the founder effect.
