Read through each scenario and answer the following questions: a. Determine the genotypes of all individuals discussed in each scenario in addition to yours, your partners’, and your unborn child. For example, “You remember your partner telling you that their father died at an early age of Huntington’s disease.” In this case you would need to determine your partner’s father’s genotype. b. Determine what probability your unborn child will inherit the disorder (be sure to include a Punnett square)? i. If you are unable to determine your child’s chance of inheriting the disorder what additional information do you require? c. Are you worried about your or your partner’s risk of inheriting the disorder (this is particularly a concern for Huntington’s disease and Marfan Syndrome)?

Problem 3. If a woman is hemophiliac, she will give birth to only hemophiliac sons regardless of the genotype of the father. Construct a Punnett squares to confirm this. There should be two of them. a) Construct a Punnett Square - List gametes in the area with the dashed line and the genotypes of the offspring in the area with the solid line.     b) Construct a Punnett Square - List gametes in the area with the dashed line and the genotypes of the offspring in the area with the solid line.

PRACTICE QUESTIONS: Please show your work on Punnett squares wherever required. GENETICS 1. Name the scientist sometimes described as the "pioneer" of genetics. 2. Define the following terms: a) genotype b) phenotype d) dominant e) recessive c) allele 1. In humans normal thumbs (T) are dominant over hitch-hiker thumbs (t). A homozygous normal thumbed female is crossed with a male with hitch-hiker thumbs. What are the genotype and phenotype ratios of the F1 generation? Of the F2 generation? 2. In guinea pigs black fur (B) is dominant over white fur (b). Short hair (S) is dominant over long hair (s). If heterozygous female is crossed with a guinea pig with white and heterozygous short fur, what will be the phenotype ratio of the F1 generation? 3. Japanese four-o-clock's are an example of a plant that displays incomplete dominance. Plants can have red flowers (R) or white flowers (W). The heterozygous condition results in pink flowers. What would be the genotype and phenotype ratios of…

There should be two of them. a) Construct a Punnett Square - List gametes in the area with the dashed line and the genotypes of the offspring in the area with the sold line.     b) Construct a Punnett Square - List gametes in the area with the dashed line and the genotypes of the offspring in the area with the sold line. Please show in the actual punnett square table!

Phenotypes associated with polygenic traits:   Question 24 options:   Result from contributions of multiple genes.   are usually dominant and recessive.   always result in threshold traits.   Can always be easily categorized.   Can be studied in individual patients.
