Zygosity is a state of similarity for genes which express a trait or characteristic called alleles on partner chromosomes. Heterozygous means having different sets of alleles expressed as genes on specific loci on a common point in a chromosome. This is important in reproduction for tracing hereditary genetic issues, because one chromosome comes from each parent. Heterozygous alleles therefore act as indicators to states of inherited characteristics. |
Examples of Heterozygous:

Population studies of incidence of genes: The incidence of a particular heterozygous gene is defined as the number of subjects in a population containing this heterozygous structure. For example, if 50 out of 100 people have the gene, the formula is H = 0.5. https://en.wikipedia.org/wiki/Zygosity#Heterozygous |

Heterozygous individuals carrying the Sco1, Sco5, Sow3 and Whc1 mutations display white spotting on the belly and a white forehead blaze while homozygotes (-/-) have a white coat color with black eyes. |
