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?
Codominance refers to traits that are expressed at the same time in heterozygotes (individuals with one copy of each allele). In this case, both the yellow kernels and the white kernels are expressed in the phenotype.
Genetic recombination (also known as genetic reshuffling) is the exchange of genetic material between different organisms which leads to production of offspring with combinations of traits that differ from those found in either parent.
Incomplete dominance is a form of intermediate inheritance in which one allele for a specific trait is not completely expressed over its paired allele.
Chimerism is a condition when a single organism is composed of cells with distinct genotypes.
