impact event formed the Chesapeake Bay area?
A)

B)
A layer of iridium and shocked quartz is present in sedimentary layers from
35 million years ago
C)
Uranium in the sediment layers older than 35 million years are emitting
low levels of radiation

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
