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



the trait occurs at a frequency of 1 in 200 in certain Hopi villages of Black Mesa in Arizona. Explain in terms of
v# v# v# v# v# v# v# v# v# v# v# v# v# v# v# v# v# bn v# v# v# v# v#



natural selection why albinism is so rare in most human populations.
v# v# v# v# v# v# v# v# bn v#




ANSWER: In most populations, there is fairly strong selection against albinism because albinos don’t produce m e
v# v# v# v# v# v# v# v# v# v# v# v# v# v# v# v#



lanin, causing their skin cells not to be protected from the damaging effects of sunlight. Also, the la c
v# v# v# v# v# v# v# v# v# v# v# v# v# v# v# v# v# v#



k of melanin in their eyes causes them to have poor eyesight. Finally, in most cultures albinos are s e
v# v# v# v# v# v# v# v# v# v# v# v# v# v# v# v# v# v# v#



en as abnormal, and they are not normally sought out for marriage and mating. Therefore, in most po

pulations the alleles that cause albinism are selected against, and they decrease in frequency or are ke
v# v# v# v# v# v# v# v# v# bn v# v# v# v# v# v#



pt at a low level, causing the recessive trait to be rare.
v# v# v# v# v# v# v# v# v# v# v#




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



the trait occurs at a frequency of 1 in 200 in certain Hopi villages of Black Mesa in Arizona. Explain in terms of
v# v# v# v# v# v# v# v# v# v# v# v# v# v# v# v# v# v# v# v# v# v# v#



natural selection why the trait is so much more common among the Hopis of Black Mesa.
v# v# v# v# v# v# v# v# v# v# v# v# v# v# v#




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



viewed as especially pretty, clean, and intelligent, and they often occupy positions of leadership.
v# v# v# v# v# v# v# v# v# v# v# v# v# v#



Albinos are celebrated in the villages as a sign of purity of Hopi blood in the community.
v# v# v# v# v# v# v# v# v# v# v# v# v# v# bn v#



Furthermore, albinos are often excused from normal male field labor because of their sensitivity to s v# v# v# v# v# v# v# v# bn v# v# v# v# v# v# v#



unlight, causing them to be left behind in the village with the women during the daytime. This allo
v# v# v# v# v# v# bn v# v# v# v# v# v# v# v# v# v# v#



ws them extra mating opportunities compared to the other men of the village. Therefore, the alleles
v# v# v# v# v# v# v# v# v# v# v# v# v# v# v# v#



that cause albinism are either selected for in this culture or at least not selected against as strongly a
v# v# v# v# v# v# v# v# v# v# v# v# v# v# v# v# v# v# v#



s in other cultures, allowing the trait to occur at a much higher frequency.
v# v# v# v# v# v# v# v# v# v# v# v# v#
