heterozygous

Having a difference in the loci, (location of the genes on a chromosome,) of one or more chromosomes. Can also be used to refer to a heterozygote. Note how hetero=different and zygous means referring to a zygote or it's characteristics.

Wow, these heterozygotes have lots of different loci.

heterozygosity

the possession of two different alleles of a particular gene or genes by an individual.

There was little correlation between current levels of inbreeding or reduced heterozygosity and prevalence of genetic disease.
