In areas of heavy use of the insecticide DDT, fly populations may show marked resistance to the
DDT over a period of time. Someone who accepts
the evolutionary theory of Lamarck would most
likely explain this observation using the concept of
A natural selection
B. inheritance of acquired characteristics
C. overproduction of a species
D.
a change in the gene frequencies

Suppose that on a small island off the coast of scotland, 32 percent of the population has blue eyes, which means that these individuals must be homozygous for the blue eye color gene (bb). the only other eye color found on the island is brown, and individuals that are homozygous for the brown eye color gene (bb) or heterozygous (bb) will have brown eyes because brown is the dominant gene. assume this population is in hardy-weinberg equilibrium. if 100 babies are born next year, how many of these would you expect to have brown eyes and be heterozygous? a. 58 b. 49 c. 29 d. 43
