Pattern of inheritance where two dominant alleles are expressed side by side-

• sex-linked

• co-dominance

• incomplete dominance

• dominant/recessive

More males are colorblind than women is because-

• the allele for colorblindness is dominant and found on the y chromosome

• the allele for colorblindness is dominant and found on the X chromosome

• the allele for colorblindness is recessive and found on the X chromosome

• Fathers can only pass the gene for colorblindness
