1. Albinism is rare in most human populations, occurring at a frequency of about 1 in 20,000 people. However, th
dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt



e trait occurs at a frequency of 1 in 200 in certain Hopi villages of Black Mesa in Arizona. Explain in terms of natur
dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt



al selection why albinism is so rare in most human populations.
dt dt dt dt dt dt dt dt dt dt




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



anin, causing their skin cells not to be protected from the damaging effects of sunlight. Also, the lack o
dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt



f melanin in their eyes causes them to have poor eyesight. Finally, in most cultures albinos are seen as
dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt



abnormal, and they are not normally sought out for marriage and mating. Therefore, in most populatio
dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt



ns the alleles that cause albinism are selected against, and they decrease in frequency or are kept at a lo
dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt



w level, causing the recessive trait to be rare.

2. Albinism is rare in most human populations, occurring at a frequency of about 1 in 20,000 people. However, th

e trait occurs at a frequency of 1 in 200 in certain Hopi villages of Black Mesa in Arizona. Explain in terms of natur
dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt



al selection why the trait is so much more common among the Hopis of Black Mesa.
dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt




ANSWER: Albinos occupy a privileged position among the Hopis of Black Mesa. In this culture, albinos are vi
dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt



ewed as especially pretty, clean, and intelligent, and they often occupy positions of leadership. Alb
dt dt dt dt dt dt dt dt dt dt dt dt dt dt



inos are celebrated in the villages as a sign of purity of Hopi blood in the community.
dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt



Furthermore, albinos are often excused from normal male field labor because of their sensitivity to sun dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt



light, causing them to be left behind in the village with the women during the daytime. This allows the
dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt dt



m extra mating opportunities compared to the other men of the village. Therefore, the alleles that caus

e albinism are either selected for in this culture or at least not selected against as strongly as in other c

ultures, allowing the trait to occur at a much higher frequency. dt dt dt dt dt dt dt dt dt dt
