pubmed-article:7429069 | pubmed:abstractText | Expression of a mammalian cross-reactive H-Y antigen on the surface of cells derived from the male guppy ((Lebistes reticulatus) is demonstrated. This finding further establishes the evolutionary conservation of H-Y antigen among lower vertebrates and provides a basis for speculation on the possible evolutionary association between H-Y antigen and sex determination. | lld:pubmed |
