The populations differ in population size as follows.    Population 1 Population 2 Population size 600 420,000  If population size of Population 1 increases to become similar to that of Population 2, what do you predict will happen to genetic variation (in terms of heterozygosity and alleles per gene) in Population 1?   A.) Genetic variation will decrease in Population 2. B.) Genetic variation will decrease in Population 1. C.) Genetic variation will stay the same in Population 1. D.) Genetic variation will increase in Population 1.

2. Dwarf lupine, a California wildflower, commonly has blue flowers, but some plants produce pink flowers. Flower color is controlled by one gene with blue dominant and pink recessive. One population has 3,291 plants with blue flowers and 25 plants with pink flowers, resulting in a total of 3,316 plants. Assuming that the population is in Hardy-Weinberg equilibrium, what is the expected number of plants that are heterozygous? Do you understand how to calculate the answer as being 526 plants?
