1/9 Warm Up Match the definition on the left with the term on the right: 1. Alternative form of a gene C A. Gamete 2. Body cells such as a skin cell E B. gene 3. Egg or sperm cell A C. allele 4. Process that produces 4 cells G D. Aa 5. A segment of DNA B E. somatic 6. Homozygous alleles F F. AA 7. Heterozygous alleles D G. Meiosis 1/10 Warm Up 1. In cats, short hair is dominant to long hair. Cross a heterozygous cat with a cat with long hair. Include a key, genotype, phenotype, percent, ratio and fraction. 2. In mice, black fur is dominant to brown fur. Cross a pure bred black fur mouse with a pure bred brown fur mouse. 1/11 or 1/12 Warm Up 1. Foil the following gametes: (Bb)(FF) X (bb)(ff) 2. Show the punnett square and predict the offspring of B=brown eyes and F=freckles. 1/13 Warm Up 1. Explain the difference between incomplete dominance and codominance. Incomplete = both alleles are expressed and the phenotype is a “blend” Codominance = both alleles are expressed and the phenotype is a mixture or patches of both of them 2. What cross will produce the most pink-flowered plants? Show a punnett square to support your answer. 3. In some chickens, the gene for feather color is controlled by codominance. The allele for black is B and the allele for white is W. The heterozygous phenotype is known as erminette. • What is the genotype for black chickens? ____ • b. What is the genotype for white chickens? ____ • c. What is the genotype for erminette chickens? ____
