5. high frequencies of rare genetically inherited traits in people who share a
common ancestor is most likely the result of:
a. natural selection
b. the founder principle
c. genetic drift
d. huntington's disease

Genetic drift

Explanation:

It is the change in the frequency of an existing gene in a population due to random sampling of organisms. Genetic drift may result in gene variants disappearing completely and thereby reducing genetic variation. It can also cause initially rare alleles to become much more frequent and even fixed in people with a common ancestry.

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
