Found Heterozygosity 5 times.

1. Codominance (codominant genes)
Two allele s of a gene which result in distinctly different phenotype s, but when they are both inherited together in an individual (one from the mother and one from the father - called heterozygosity ), the individual has both of the phenotypes. For example, if one allele is for red hair and the other allele is for blue hair, then the individual will have patches of blue hair and patches of red hair. (This is in contrast to incomplete dominance , where the individual would inherit a blend of the two alleles and have purple hair).

2. Heterozygosity
The condition of being heterozygous .

3. Heterozygosity
The presence of different allele s at one or more loci on homologous chromosome s.

4. Hybrid enzyme
An enzyme in a heterozygous individual which has subunits with slightly different sequences of amino acid s than other copies of the same enzyme. This occurs because the two allele s of the gene s which code for each subunit are slightly different (due to the heterozygosity), so that either of the two versions of the subunit could be produced for any copy of the enzyme.

5. Incomplete dominance
Two allele s of a gene which result in distinctly different phenotype s, but when they are both inherited together in an individual (one from the mother and one from the father -- called heterozygosity ), the individual ends up with a blend of the two phenotypes. For example, if one allele is for red hair and the other allele is for blue hair, then the individual will have purple hair. (This is in contrast to codominance , where the individual would inherit patches of blue and patches of red hair).
