Question
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 the F1 generation from cross between a white plant and a pink plant. 4. In cattle the alleles for red hair and white hair are co-dominant. The heterozygous condition is known as "roan". If a roan parent is crossed with a red parent, what will be the genotype and phenotype ratios of the F1 generation?
