Corn has two color alleles (yellow and white. A farmer crosses a yellow corn plant (yy) with a white corn plant (ww) to produce a corn plant (offspring with yw genotype) which exhibits equal numbers of white and yellow kernels. This is an example of:

CO-DOMINANCE

This is an example of co-dominance.

Here the alleles in the heterozygous plant are fully expressed i.e. the effect if each allele are is not modified by the presence of the other.

This also *results in three distinct phenotypes.

When the yellow colour plant (yy) is crossed with the white colour plant,they undergo codominance which resulted in the following genotype:

1. Yellow colour plant (yy)

2. White colour plant(ww)

3. A corn plant which exhits equal numbers of white and yellow kernels (yw).

Codominance is a form of inheritance wherein the alleles of a gene pair in a heterozygote are fully expressed. As a result, the phenotype of the offspring is a combination of the phenotype of the parents. Thus, the trait is neither dominant nor recessive.

Answer:co dominance in corn

Step-by-step explanation:

Co dominance occurs when both alleles are dominant that is the codominants traits are express equally in the phenotype. As seen in the corn, the offspring has equal phenotype yw
