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).

The entire cardiac cycle is as follows:

  1. Deoxygenated blood enters the right ventricle from the superior and inferior vena cava.
  2. The right atrium pumps the deoxygenated blood to the right ventricle.
  3. From the right ventricle, the deoxygenated blood moves to the lungs via the pulmonary artery.
  4. After gaseous exchange, the oxygenated blood returns to the heart into the left atrium via the pulmonary vein.
  5. From the left atrium, blood moves to the left ventricle.
  6. Oxygenated blood is pumped by the left ventricle into the aorta which supplies blood to all parts of the body.
  7. Deoxygenated blood, collected from the body again enters into the right atrium via the vana cava.
