Answer

Dominance: one allele expresses itself in the hybrid heterozygous condition, other is suppressed.
Co dominance: both the alleles of a gene express in a heterozygous hybrid containing two dominant alleles.
Incomplete dominance: Neither of the two alleles of a gene is completely dominant over the other in heterozygous condition, the hybrid is intermediate.
