hy·pos·ta·sis
(hi-pos'tă-sis),1. Formation of a sediment at the bottom of a liquid.
2. Synonym(s): hypostatic congestion
3. The phenomenon whereby the phenotype that would ordinarily be manifested at one locus is obscured by the genotype at another epistatic locus; for example, in humans, the phenotype for the ABO blood group locus can be expressed only in the presence of its precursor, H substance. The Bombay factor in the homozygous state blocks H formation and obscures the ABO phenotype.

hypostasis
a relationship between two genes whose products act in the same biochemical PATHWAY, where the functional effect of one gene is masked by another. The enzyme coded by the hypostatic gene operates later in the pathway than the enzyme produced by the epistatic gene. see EPISTASIS.Collins Dictionary of Biology, 3rd ed. © W. G. Hale, V. A.
