The genetic variations seen in and between populations are known as human genetic variation.
Humans differ genetically from one another. Due to developmental mutations and gene copy-number variation, even monozygotic twins, who arise from a single zygote, may differ genetically. Techniques like genetic fingerprinting rely on individual differences, even between closely related people.
There are 324 million identified variations from sequenced human genomes as of 2017.
A person's genome typically differs from the reference genome by 20 million base pairs, or 0.6% of the total 3.2 billion base pairs, as of 2015.
In contrast to other species, humans are genetically uniform. While a limited number of genetic variations are found more commonly in particular geographic regions or in individuals with ancestry from those places, this variance accounts for the majority of genetic variation.
Genetic variation between populations occurs for at least three reasons. If an allele offers a competitive advantage, natural selection may endow people with an adaptive advantage in a particular environment.

Answer:
Incomplete dominance
Explanation:
A phenotypic "blending" of two traits is referred to as incomplete dominance, indicating that neither trait is truly dominant over the other. Instead of one color overpowering expression of the other, both colors are expressed simultaneously.
Codominance suggests that both phenotypes are dominant, but cannot be expressed at the same time. The result of codominance would be regions of dominant red expression and regions of dominant white expression, resulting in spots rather than blending.
Mitosis occur more fast in our body. It can also meiosis occurs more in men than in women, and they splits once as meosis splits twice and they are not identical.
hope this help you out
Answer:
The interdependence of the worms and plants is an example of commensalism in a sense that as the worms burrow into the soil, it allows the soil to be<em> loosened</em> which then allows it to properly absorb water and carbon dioxide into its roots. This action <u>benefits the plants' growth.</u> However, such action of the worms,<em> neither benefit the worms nor does it cause any harm.</em>
Explanation:
"Commensalism" is a relationship between two things wherein <em>one benefits while the other is neutral</em>. This means<u> the other one doesn't benefit nor is it harmed.</u>
