How do you know a genotype is purebred
WebIncomplete dominance can occur because neither of the two alleles is fully dominant over the other, or because the dominant allele does not fully dominate the recessive allele. Co-dominance can occur because both the alleles of a gene are dominant, and the traits are equally expressed.
