Part 1: Post-Lab Questions 1. Set up and complete Punnett squares for these crosses (remember Y = yellow, y = blue): a. YY and Yy b. YY and yy 2. Answer these questions: a. What are the resulting phenotypes? b. Are there any blue kernels? C. How can you tell whether or not there are blue kernels? 3. Set up and complete a Punnett square for a cross of two of the F1 from Step 1 (above). 4. Answer these questions: a. What are the genotypes of the F2 generation? b. What are their phenotypes? C. Are there more or fewer blue kernels than in the F1 generation? 5. Identify the four possible gametes produced by the following individuals (Y = yellow, y = blue, S = smooth, s = wrinkled): a.

Laboratory 11-Questions And mo17 4. You discover a new animal that has yet to be classified. You find that the dominant allele "P" leads to the presence of long horns and the recessive allele "p" leads to the absence of horns. You also notice that the allele "L" leads to long legs and the allele "I" leads to a short-legged version of this animal. Please answer the following ques- tions based on the following cross: on PpLl (Male) x ppll (Female) What are the potential gametes for the male? a.

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…

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 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!
