In a population of lizards, in a 6-month period, 150 lizards emigrate from the
population. In the same 6-month period, 140
lizards immigrate to the population. How
did the population change during the 6-month
period? (Assume all other factors did
not change.)
A. The population decreased by 10 lizards.
B. The population increased by 140 lizards.
C. The population increased by 150 lizards
D. The population decreased by 290 lizards

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
