Hi I am studying for a biology exam and I have some questionsthat are on a review sheet that i am unsure about
1. In Tomatoes, the allele for red fruit is dominant over theallele for yellow fruit. If a plant that is homozygous for redfruit is crossed with a plant with yellow fruit â
a) what is/are the genotype(s) and the phenotype(s) of the fruitproduced in the F1 generation?
b) what is/are the genotype(s) and the phenotype(s) of the fruitproduced in the F2 generation?
c) what is the phenotypic ratio of the F2 fruit?
2. A plant with red flowers is crossed with a plant with whiteflowers. All the F1 plants produced red flowers. When the F1 plantsare allowed to self-pollinate, they produce 623 plants with redflowers and 198 plants with white flowers. What are the genotypesof the P and F1 generations?
3. In Tomatoes, the allele for red fruit isdominant over the allele for yellow fruit. Theallele for tall plants is dominant of the allele forshort plants. Find the genotypes and phenotypes ofthe F1 and F2 generations and the phenotypicratio of a cross between a homozygous dominant in both genes and ahomozygous recessive in both genes. The homozygous individuals arethe Parental generation.
4. In cocker spaniels, solid coat color is dominantover spotted coat. A veterinarian has a spaniel with a solidcoat. How can she unequivocally determine the genotype of thisanimal for coat color from a single breeding?
