Suppose that the height of a hypothetical plant is controlled by one gene with two incompletely dominant alleles. A. What phenotypes would be expected in the offspring from a cross of a tall plant and a short plant? B. What phenotypes would be expected in the offspring from a cross of two medium plants? A geneticist working at a zoo has spent several years studying coat color in foxes. She found that when two platinum-colored foxes are crossed, litters with both platinum and silver-colored offspring are always produced. Over the years, she collected the following data. platinum X platinum rightarrow 220 platinum foxes and 110 silver foxes Develop a hypothesis to explain these data. In sweet peas, the two allelic pairs C, c and P, p are known to effect pigment formation in the flowers. The dominants, C&P, are both necessary for colored flowers. Absence of either results in white flowers. A dihybrid plant is crossed to a white plant that is heterozygous at the “C” locus. a. What is the genotype of the dihybrid plant? b. What is the genotype of the white plant? c. What kinds of flowers, colored or white, are to be expected from this cross? Assume that genes C and P are on different chromosomes and include ratios in your answer.
