The type of inheritance that involves the partial expression of two different
alleles is called

Incomplete dominance

Explanation:

In incomplete dominance, both alleles are expressed but have become blended giving rise to a new trait with one also been more noticed than the other although both are expressed. For instance a red flower and a white flower are crossed, giving rise to a pink flower. As compared to codominance, both alleles are equally expressed and are equally dominant. For example, a white college crossed with a black hen giving rise to a black and white (checkered) chick.
