Summary Introduction

To review:

The differences between incomplete and co-dominance dominance.

Introduction:

The expression and interaction between alleles of the same gene can be incomplete or co-dominant. One is called as incomplete dominance because of less expression of a dominant allele in heterozygous genotype as in the case of flower color in Snapdragon, that is, pink. The other one is co-dominance because of expression of products of both the alleles, for example, in individuals with AB blood group.
