Because we know that 15% of the population does not have the allele we can assume that at least 85% of the population has at least on copy of the dominant allele.
It is true that dead zones in waterways can occur as the result of fertilizer runoff.
Answer:
humans are adapted to a wide range of environments, and genetic variation leads to phenotypic variation
Explanation:
It has been shown that the average genetic variation between human individuals is about 0.1% (i.e., one base pair out of every 1,0000 are different between any two individuals). This value seems low, but it is huge when we consider that the current estimate for the world population is 7,800,000,000 people. The phenotype is the result of the interaction between genotype and environment. Genetic variation is the raw material that enables some individuals to adapt to different environments. As species, humans have a high genetic diversity in order to develop a wide range of phenotypes well adapted to different environmental conditions.
