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.

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
