You have a cup of beans in front of you with 20 white beans and 20 red beans. (You can also use candy, buttons, or coins). These beans represent the alleles for a simple Mendelian trait, where red is dominant (R) and white is recessive (r). The cup holds the alleles for an entire population (the gene pool). Required:
a. Assess the gene pool. How many alleles of each kind are present in your overall population?

1. Dominant: 0, Recessive: 40
2. Dominant: 40, Recessive: 0
3. Dominant: 20, Recessive: 20
4. Dominant: 20, Recessive: 0
5. Dominant: 0, Recessive: 20

b. Randomly draw out five genotypes (pairs of beans) that will survive. Record the genotypes of these five individuals.
