A Mutation occurring in the population will change the allelic ratio.
<h3>What is evolution?</h3>
Evolution refers to the changes that occurs in organisms over a long period of time such that those changes results in new species better adapted to their environment and having higher specialization.
One of the factors of evolution is mutation.
According to the Hardy-Weinberg principle, the allele and genotype frequencies of a population of organism in equilibrium will remain constant in the absence of evolutionary influences.
Therefore, if a mutation occurs in the population, the allelic ratio will change.

Answer:
e. Epistatic interaction of the two genes
Explanation:
The 9:7 ratio is typical of the Duplicate Recessive Epistasis.
The expected phenotypic ratiio of the offsrping of a dihybrid cross is:
9 A_B_
3 A_bb
3 aaB_
1 aabb
In the Duplicate Recessive Epistasis, the A_bb, aaB_ and aabb individuals all have the same phenotype, making for the ratio 9:7. What those three genotypes have in common is that in all of them at least one of the two genes is homozygous recessive (either <em>aa</em> or <em>bb</em>).
This usually happens one the products of genes A and B are enzymes of the same metabolic pathway.
Whenever both A and B are present, the pathway can produce the final product and a certain phenotype. However, if any of the dominant alleles is missing, the enzyme is not produced and therefore the final product of pathway is not produced, giving the other phenotype.
D they are easily contained charges so on and off is no problemo
Answer:
Photosynthesis, Decomposition, Respiration and Combustion.
