Gene flow and genetic drift both affect allele frequencies in a population. A high level of gene flow into a population genetic

DaniilM [7]

A high level of gene flow into a population increases genetic diversity in a population. A high level of gene flow out of a population decreases genetic diversity in a population. Genetic drift is the change in allele frequencies due to "sampling error" factors. Typically, genetic drift has the biggest impact on small populations.

Gene flow (or gene migration) is a mechanism of evolution (change the allele frequencies) which transfers genetic variation among populations due to migration. High level of gene flow decreases the genetic differentiation between the two populations.

Genetic drift is a mechanism of evolution that acts by chance (“sampling error”) often when a population is reduced in size by a natural disaster (bottleneck effect) or when a small group leaves the main population and forms a colony (founder effect).

<h2>Prevent of Disease</h2>

Explanation:

People in the United States can experience diseases such as heart disease, stroke, type 2 diabetes, and some forms of cancer that are associated with Ensuring an adequate intake of fruit and vegetables should further reduce risk for oral cavity, oesophagus, stomach and colorectal cancer.
Unhealthy eating and physical latency are driving reasons for death in the U.S. Undesirable eating regimen adds to around 678,000 passings every year in the U.S. because of nourishment and weight related illnesses, for example, coronary illness, malignant growth, and type 2 diabetes.
One of the best disease fighting foods is dark, leafy greens, which incorporate everything from spinach, kale, and bok choy to dark lettuces.
They are stacked with nutrients, minerals, beta-carotene, nutrient C, folate, iron, magnesium, carotenoids, phytochemicals, and cell reinforcements.
The most widely recognized hazard factors for malignant growth incorporate maturing, tobacco, sun introduction, radiation presentation, synthetic compounds and different substances, some infections and microbes, certain hormones, family ancestry of disease, liquor, less than stellar eating routine, absence of physical action, or being overweight.
Tobacco is the main source of malignant growth, however dietary components contribute altogether to certain kinds of disease.
Keeping up a solid weight will diminish the hazard for malignant growths of the throat, colorectum, bosom, endometrium and kidney.
