The relative frequency of a particular allele in a population.

What happens if the allele is advantageous or disadvantageous?
A
If it is advantageous, the allele will be selected for and so increase the frequency.
If it is disadvantageous, natural selection will sometimes result in its removal from the gene pool.
3
Q
What could possibly happen to a disadvantageous allele if the environmental conditions change?
A
It could possibly become advantageous.
4
Q
The changes in allele frequency due to natural selection may lead to…
A
a new species emerging.
5
Q
Change in allele frequency can be due to…
A
Mutation or natural selection
