A gene for corn has two alleles, one for yellow kernels and one for white kernels. Cross pollination of yellow corn and white corn results in ears of corn that have an approximately even mix of yellow and white kernels. Which term best describes the relationship between the two alleles?
  • a)
    Genetic recombination
  • b)
    Codominance
  • c)
    Incomplete dominance
  • d)
    Chimerism

Codominance occurs when both alleles of a gene are expressed equally in the phenotype of a heterozygous individual. In the case of the corn kernels, the yellow allele and the white allele are both expressed in the phenotype, resulting in an approximately even mix of yellow and white kernels in the ears of corn. Neither allele is dominant over the other, and they are both fully expressed.
Therefore, option B, "Codominance," is the correct term to describe the relationship between the yellow and white alleles for corn kernel color.
