C57BL/Crgl mice prefer 10% alcohol to water, while C3H/Crgl/2, A/Crgl, A/Crgl/2, BALB/cCrgl, and DBA/2NCrgl mice prefer water. F-sub(1)s between C57BL and the other strains show intermediate preferences, and maternal effects do not appear to be involved. Preference data of F-sub(1)s and backcrosses lead to the conclusion that a polygenic system is involved. From Psyc Abstracts 36:02:2DP16M. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
