A plant that is homozygous for yellow seeds is crossed with a plant that is homozygous for green seeds. What percentage of the F1 generation would you expect to have yellow seeds? A plant that is heterozygous for tall stem length is crossed with a plant that has dwarf stem length. What percentage of the F1 generation would you expect to have dwarf stem length? A plant that has wrinkled seeds is crossed with a plant that is heterozygous for round seeds. What percentage of the F1 generation would you expect to have round seeds? A plant that is homozygous for tall stem length is crossed with a plant that is homozygous for dwarf stem length. What would be the phenotype of all the offspring in the F1 generation? Given that red flower color is dominant over yellow flower color. What would be the genotypic ratio of the offspring produced from a heterozygous red flowered plant and a homozygous yellow flowered plant? What would be the phenotypic ratios of the offspring produced from a heterozygous red flowered plant and a homozygous yellow flowered plant? In rabbits the allele for black coat color (B) is dominant over the allele for brown coat color (b). What would be the results of a cross between an animal homozygous for black coat color (BB) and one homozygous for brown coat color (bb)?
