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




it occurs at a frequency of 1 in 200 in certain Hopi villages of Black Mesa in Arizona. Explain in terms of natural select
K K K K K K K K K K K K K K K K K K K K K K K




ion why albinism is so rare in most human populations.
K K K K K K K K K




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




n, causing their skin cells not to be protected from the damaging effects of sunlight. Also, the lack of mela
K K K K K K K K K K K K K K K K K K K




nin in their eyes causes them to have poor eyesight. Finally, in most cultures albinos are seen as abnormal,
K K K K K K K K K K K K K K K K K K




and they are not normally sought out for marriage and mating. Therefore, in most populations the alleles t
K K K K K K K K K K K K K K K K K K




hat cause albinism are selected against, and they decrease in frequency or are kept at a low level, causing t
K K K K K K K K K K K K K K K K K K K




he recessive trait to be rare. K K K K K




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




it occurs at a frequency of 1 in 200 in certain Hopi villages of Black Mesa in Arizona. Explain in terms of natural select
K K K K K K K K K K K K K K K K K K K K K K K




ion why the trait is so much more common among the Hopis of Black Mesa.
K K K K K K K K K K K K K K




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




ed as especially pretty, clean, and intelligent, and they often occupy positions of leadership. Albinos a
K K K K K K K K K K K K K K K




re celebrated in the villages as a sign of purity of Hopi blood in the community.
K K K K K K K K K K K K K K K




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




ht, causing them to be left behind in the village with the women during the daytime. This allows them extr
K K K K K K K K K K K K K K K K K K K




a mating opportunities compared to the other men of the village. Therefore, the alleles that cause albinis
K K K K K K K K K K K K K K K K




m are either selected for in this culture or at least not selected against as strongly as in other cultures, allo
K K K K K K K K K K K K K K K K K K K K




wing the trait to occur at a much higher frequency. K K K K K K K K K
