1. In what populations do we see the high frequencies (above 80%) of the allele associated with lighter pigmentation?
Japanese
Indonesian
Italian
Chinese
Mongolian
India
African
German
Bangladesh
Turkish
French
2. Why might some light-skinned populations, such as the Japanese, be missing F374 allele?
a. There have been multiple, different mutations that have produced light skin in different populations
b. This allele does not cause depigmentation
c. Some populations, such as Japanese, are only light-skinned because they avoid tanning
d. The sampling of Japanese in this study probably did not capture the true incidence of the F374 allele in the population.
3. What are acclimatizations to high altitude? Choose all correct.
a. larger lungs
b. increased respiration
c. increased production of red blood cells
d. larger heart
1) In german, french, italian, japanese,chinese and turkish populations (in that order aproximate) the alleles associates with lighter pigmentation present high frequencies, giving phenotypes of lighter skins.
2) Considering that people who have the F374 allele mutation in the SLC45A2 gene, have as a result a ligher skin. Other mutations in other populations can also cause lighter pigmentation, so option a.
3) Acclimatizations to high altitude includes:
a) larger lungs
b) increse respiration and
c) increased production of red blood cells.

Can I get a summary of this article name "Evolution Is Happening Faster Than We Thought" By MENNO SCHILTHUIZEN? — A FRIEND recently invited me over to see the blackbird that had taken up residence in a potted plant on her balcony. Serenely incubating eggs in the inner city, this bird had little in common with its shy, reclusive ancestors that nested in Europe’s forests. Early in the 19th century, probably in Germany, blackbirds began settling in cities. By the...
