Incomplete Dominance

What Is Incomplete Dominance?

This is a form of inheritance in a cell where one allele (form of gene) for a specific trait is not dominant over the other allele, which in conclusion makes a combined phenotype (physical trait).  

Confused? Above is an example. When you cross pollinate between a red and a white snapdragon plant, the offspring will be pink. This is because the red allele is not completely dominant over the white allele, so because of that the two allele's are combined to make the outcome of a pink flower.
