You do not need to plan. that was a false statement
Genetic drift occurs when there is no random mating across a population. This causes a change in allelic frequency due to a random sampling of the population.
As the aboriginal population explored the earth, a small part of the population became geographically isolated either due to continental drift and climate changes. As the isolated population grew bigger, they established their own gene pool. This resulted a change in genotypic frequencies from that of the aboriginal population.
epistatic gene
Explanation:
Some genes mask the expression of other genes just as a fully dominant allele masks the expression of its recessive counterpart. A gene that masks the phenotypic effect of another gene is called an epistatic gene; the gene it subordinates is the hypostatic gene.
Answer:
Explanation
A climax community (Figure below) is the end result of ecological succession. The climax community is a stable balance of all organisms in an ecosystem and will remain stable unless a disaster strikes. After the disaster, succession will start all over again.
