Analysis of Quantitative Inheritance of Body Size in Mice. II. Gene Action and Segregation.

OMINANCE deviation in continuously varying characters is a matter which D is of great concern to both animal and plant breeders, for dominance of the favored gene is an aid to selection when the gene frequency is low, but a hindrance when the gene frequency is high (LUSH 1947). At present, theory of the consequences in quantitative traits is further advanced than is experimental observation. Fo...
