Chapter 01: Introduction to Genetics
1. Albinism is rare in most human populations, occurring at a frequency of about 1 in 20,000
people. However, the trait occurs at a frequency of 1 in 200 in certain Hopi villages of Black Mesa in
Arizona. Explain 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 produce melanin, causing their skin cells not to be protected from the damaging effects of
sunlight. Also, the lack of melanin in their eyes causes them to have poor eyesight. Finally, in most
cultures albinos are seen as abnormal, and they are not normally sought out for marriage and
mating. Therefore, in most populations the alleles that cause albinism are selected against, and they
decrease in frequency or are kept at a low level, causing the recessive trait to be rare.
a. evolution—population genetics
b. gene regulation—molecular genetics
c. allelic frequency alteration—population genetics
d. arrangement of genes on chromosome—transmission genetics
e. chemical nature of the gene—transmission genetics

6. Identify a TRUE statement from the following descriptions concerning genetics.
a. The theory of pangenesis states that all living organisms are composed of cells.
b. Bacteria and viruses are not useful in studying genes and inheritance because they are
structurally and metabolically different from eukaryotic cells.
c. Charles Darwin accurately described the laws of inheritance in his landmark book, On the
Origin of Species.
d. Many human traits, such as skin and hair color, are determined by more than a single gene.
e. Evolution can occur without genetic changes in the population.
ANSWER: d
