- The dominant C allele of a gene that controls color in corn produces kernels with color; plants homozygous for a recessive c allele of this gene have colorless or white kernels. What kinds of gametes, and in what proportions, would be produced by the plants in the following crosses? What seed color, and in what proportions, would be expected in the offspring of the crosses? a. CCCc b. Cccc c. CcCc1. The height of a wheat plant is determined by several genes. In a variety the minimum size is 12 inches and the maximum is 24 inches. 12-inch plants were crossed with 18-inch plants, and produced an 18-inch F1. The F1 was allowed to cross each other, and an F2 was obtained in which the 12 and 24 inch plants were obtained with a frequency of 2/8195. How many genes are involved in determining plant size in this variety of wheat? Select one: a. 5b. 6c. 4d. 38. Kernel color in wheat is controlled by 2 pairs of genes (AABB).
