Dominant genes overrule others. Recessive genes are part of your genes, but not usually expressed if the dominant overrules it.

What's the difference between incomplete dominance and codominance?

In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in phenotype
