Answer:

C

Explanation:

Before the earthquake the gene pool of the parent population was bigger and carried different alleles for a lot of genes.

After the killing of 98% of the population, the surviving one has an incomplete representation of the original gene pool. We can think of this as a gene bottleneck ; the new allele frequencies will be different that the parental population. IE: broadness of stripes has a higher frequency after the earthquake.

What relationship between both an abiotic and a biotic factor in a ecosystem?
likoan [24]

Answer:

Abiotic factors are all of the non-living things in an ecosystem. Both biotic and abiotic factors are related to each other in an ecosystem, and if one factor is changed or removed, it can affect the entire ecosystem. Abiotic factors are especially important because they directly affect how organisms survive.
