Absence of Gene Interaction in Mouse Hybrids, Revealed by Studies of Immunological Tolerance and Homotransplantation.

Abstract
Summary and conclusions 1. C3H mice made tolerant by injection of A spleen cells at birth are tolerant of skin homografts from A strain and (A x C3H) F1 donors. 2. C3H mice made tolerant by injection of (A x C3H) F1 spleen cells at birth are tolerant of skin homotransplants from both A strain and (A x C3H) F1 donors. These observations are interpreted as evidence indicating that new histocompatibility antigens do not derive from genie interaction during hybridization in the 2 inbred strains of mice in these studies.
