Question

if a mutation appears in one individual that changes one base in a dna sequence to another base in a DNA sequence ot another base, and the population is evolving by genetic drift, over time that mutation will

Answer 1

A mutation that changes one base in a DNA sequence to another base can introduce a new allele to a population. Over time, the frequency of the new allele can change due to genetic drift.

Step-by-step explanation:

Mutation is a source of new alleles in a population. A mutation is a change in the DNA sequence of a gene. When a mutation occurs in one individual, changing one base in a DNA sequence to another base, it introduces a new allele to the population. Over time, the mutation can change the frequency of the allele in the population due to genetic drift.

Genetic drift is the effect of chance on allele frequencies in a population. It is most important in small populations. By chance, some individuals may have more offspring than others, not due to any advantage conferred by a genetically-encoded trait, but just due to random factors. If an individual with the new allele happens to have more offspring, the frequency of that allele can increase over time through genetic drift.

Answer 2

The mutation will be fixed by genetic drift.

Step-by-step explanation:

Genetic drift is the change in the allele frequencies in a population that occur randomly. It is an evolutionary process (like natural selection), that is associated with the reduction in genetic diversity by the fixation of rare allelic variants and neutral mutations. In this example, this point mutation is neutral since, according to data, the population is evolving by genetic drift. Moreover, it is also important to note that a mutation that involves one nucleotide is also called Single Nucleotide Polymorphism (SNP).
