| Summary: | A review is presented of the genetic of
growth, effects of long and short-term selection experiment under different feeding regimes on weight gain, feed efficiency and food consumption in mice. The genetic parameters considered are; nature and extend of within and beetwen line genetic variation for body weight and growth rate; correlated response to se!ection for body weight, weight gain, fe ed intake and fe ed efficiency. The relationsphips of fe ed efficiency with other traits is reviewed
at length.<p>
The response of characters to se!ection in the
short-term differ qualitatively from those in the Jang term. In the short term, the respanses depend on genetic corre!ations between characters, but in the Jang- term they are only determined by fitness function of natural and directional selection, indepent of genetic and phenotypic corre!ations. |
