plain in terms of natural selection why albinism is so rare in most human populations.

ANSWER: In most populations, there is fairly strong selection against albinism because albinos don’t pr

oduce melanin, causing their skin cells not to be protected from the damaging effects of su
QU QU QU QU QU QU QU QU QU QU QU QU QU QU QU



nlight. Also, the lack of melanin in their eyes causes them to have poor eyesight. Finally, in
QU QU QU QU QU QU QU QU QU QU QU QU QU QU QU QU QU



most cultures albinos are seen as abnormal, and they are not normally sought out for marri
QU QU QU QU QU QU QU QU QU QU QU QU QU QU QU



age and mating. Therefore, in most populations the alleles that cause albinism are selected
QU QU QU QU QU QU QU QU QU QU QU QU QU QU



against, and they decrease in frequency or are kept at a low level, causing the recessive trai

plain in terms of natural selection why the trait is so much more common among the Hopis of Black

Mesa.
ANSWER: Albinos occupy a privileged position among the Hopis of Black Mesa. In this culture, albin
QU QU QU QU QU QU QU QU QU QU QU QU QU QU QU



os are viewed as especially pretty, clean, and intelligent, and they often occupy position
QU QU QU QU QU QU QU QU QU QU QU QU QU



s of leadership. Albinos are celebrated in the villages as a sign of purity of Hopi blood in
QU QU QU QU QU QU QU QU QU QU QU QU QU QU QU QU QU



the community.
QU QU



Furthermore, albinos are often excused from normal male field labor because of their sensit
QU QU QU QU QU QU QU QU QU QU QU QU QU



ivity to sunlight, causing them to be left behind in the village with the women during the d

age. Therefore, the alleles that cause albinism are either selected for in this culture or at le
