Zebra mussels (Dreissena polymorpha) are originally native to Russia. In the mid-1980's, zebra mussels were introduced into the Great Lake region of the United States where they rapidly reproduced; females can produce up to one million eggs per year. In one zebra mussel population, most of the individuals have dark, zebra-striped shells (genotype AA). However, solid light-colored shells (genotype aa) occur in 1 of every 10,000 individuals. The solid light-colored shells indicate mussels that are not hardy in cold water temperatures (<15oC). In a population of 10,000 mussels, how many individuals would be heterozygous and contain the recessive gene that might potentially help rid the Great Lakes of this invasive species? A) 198 B) 205 C) 200 D) 350
