Part 1. The Female Monster In this part of the exercise, you will create the genotype of a female monster by flipping a coin to randomly select the alleles for six different characteristics. Procedure: 1. For each of the six characteristics in Table 1, flip a coin twice to determine the genotype, and record it in the table. Heads = allele 1, and tails = allele 2. For example, if you flipped heads twice, your monster will have two copies of allele 1 for that characteristic. If you get heads for one flip and tails for the other, then the genotype would be heterozygous (one of each allele). Two tails would mean two copies of allele 2. • NOTE: be very careful to clearly indicate whether the allele is an upper case letter or a lower case letter (such as in the C/c and Y/y pairs). 2. After you have entered the genotypes into the table, determine the phenotype for each characteristic based on those genotypes, and add that to Table 1. Pay attention to the type of inheritance indicated in each case (complete dominance, incomplete dominance, or codominance). Table 1. Genotypes and Phenotypes for the Female Monster Characteristic Allele 1 Allele 2 Genotype Phenotype Two small eyes (E) One large eye (e) Allele 1 Red (R) White (R’) heterozygous Number and size of eyes (complete dominance) Eye color (incomplete dominance) Skin color (codominance) Tail shape (complete dominance) Number of toes (incomplete dominance) Green (G) Blue (B) heterozygous Curly (C) Straight (c) Allele 2 Four toes (F) Two toes (F) Allele 1 Ear shape (complete dominance) Pointy (Y) Rounded (y) Allele 2 Part 2. The Male Monster The female monster you created in Part 1 and a male monster (see Table 2 below) plan to have baby monsters. They are interested in finding out, for each characteristic, the probability that their offspring will have a particular trait. Procedure: 1. Fill in the missing information in Table 2 for the male monster. Table 2.

Explanation– The female monster will have two small pink color eyes, the body will be green blue with a straight tail, four toes and rounded ears.

The male monster will have one large white color eye, green body with straight tail, 3 toes and a pointy ears.

Explanation– The baby will have two small eyes and the color can be either pink or white. The body color can either be green or green blue, and the tail will be straight. The number of toes can be either 4 or 3 and the ears will always be pointy.
