zy·gos·i·ty Z0031450 (zī-gŏs′ĭ-tē)n. The genetic condition of a zygote, especially with respect to its being a homozygote or a heterozygote.zygosity (zaɪˈɡɒsɪtɪ) n (Genetics) genetics the similarity or differences between DNA sequences on the chromosomes of a fertilized eggzy•gos•i•ty (zaɪˈgɒs ɪ ti, zɪ-)
n. 1. the characterization of a hereditary trait in an individual according to whether the gene pairs for the trait are homozygous or heterozygous. 2. the characterization of twins, triplets, etc., according to whether they are monozygotic or dizygotic.

zygosity [zi-gos´ĭ-te] the condition relating to conjugation, or to the zygote, such as (a) the state of a cell or individual in regard to the alleles determining a specific character, whether identical (homozygosity) or different (heterozygosity); or (b) in the case of twins, whether developing from one zygote (monozygotic" >monozygotic twins) or two zygotes (dizygotic twins).zy·gos·i·ty (zī-gos'i-tē), The nature of the zygotes from which individuals are derived; for example, whether by separation of the division of one zygote (monozygotic), in which case they will be genetically identical, or from two separate zygotes (dizygotic).zygosity (zī-gŏs′ĭ-tē)n.
