title: Allelic structural genes for the expression of mature of immature endogenous type-C virus in C57BL/he and C57BL/6J mice.
abstract: Type C particles produced in a great amount by the exocrine pancreas of normal C57BL mice have been found by electron microscopy to retain their immature morphology in C57BL/6J mice and to develop into the mature form in C57BL/He mice. Examining F1, F2 and BC1 hybrids between the 2 strains, evidence of a dominant allelism for the immature phenotype was found.
