Genetic Consequences of Crossbreeding1,2,

R. L. Willham

Iowa State University, Ames

Abstract

Crossbreeding produces some desirable consequences. They are the production of heterosis, the opportunity to incorporate desirable genetic material quickly, and the chance to combine several desirable traits into a market animal. The primary factor involved in each consequence is genetic divergence as measured by gene frequency difference among the groups. The degree of dominance is important in the production of heterosis and combining several desirable traits.
