An analysis of the response to selection for high and low rate of gain in the mouse, Mus musculus

Creator:: Burrill, Melinda Jane
Abstract:: An experiment was conducted to examine the responses to selection for high and low rate of gain in the mouse under a system whereby inbreeding was maximized. Rate of gain was measured by an index designed to include gains in both the pre- and postweaning periods with the gains in...
