Detailed explanation-1: -Expert-Verified Answer. The term that best describes the relationship between the two alleles is Codominance. In heterozygotes, codominance refers to features that are expressed at the same time (individuals with one copy of each allele).
Detailed explanation-2: -Kernel color in corn is a trait determined by two alleles. The dominant allele (P) produces a purple color, and the recessive allele (p) produces a yellow color. The diagram below shows an ear of corn produced by crossing two corn plants. The shaded kernels are purple, and the unshaded ones are yellow.
Detailed explanation-3: -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.
Detailed explanation-4: -Yellow is recessive because it does not show up in the parental cross (F1 generation), and there are 3 times fewer yellow kernels in the F2 generation.
Detailed explanation-5: -Summary of the four genes, Pr1, R1, C1 and Y1, influencing kernel color.
