1.Let us say mice come in two coat colors, tan and black. Tan is the dominant allele (T) and black (t) is the recessive allele. In a population of 200 mice, there are 25 black mice. What is the expected frequency of heterozygous tan mice in this population?

2(a).The beak color of finches come in two different phenotypes, black and yellow. Black beaks (B) are dominant over yellow beaks (b). In a population, there are 210 individuals with BB genotype, 245 with Bb genotypes and 45 with bb genotype. What is the frequency of the recessive allele in this population? What is the frequency of the dominant allele?

2(b).The next generation of finches has a population of 400 finches. There are 336 finches with black beaks and 64 with yellow beaks. Is this population in Hardy-Weinberg equilibrium? Explain why or why not.

3.Walking through the forest, you find a large population of toadstools. Since you are a fungi expert you know that the allele for a spotted toadstool is dominant (T) over the allele for being plain (t). You count 1007 toadstools. Of these, you find 14 plain toadstools. What are the allele and genotype frequencies for this toadstool population?
