When alleles are codominant, both forms of the gene show up. For instance, cattle can have red hairs or white hairs. A red cow is RR. A white cow is WW. A cow with both alleles, RW, has both red and white hairs and is called roan.

When alleles have incomplete dominance, you will see an intermediate form of the trait. Red flowers, RR, crossed with white flowers, WW, produce pink flowers, RW.

Genotype means the combination of genes or alleles in an organism. Tt and BB are examples of genotypes.

Phenotype means the form of the trait that results. Say the phenotype in words instead of letters. Tall and red are phenotypes.
