Abstract

Lines of mice divergently selected for 10 week body weight were investigated for the presence of segregating alleles with large effect on weight. It appears that the X chromosome may act as a "major gene" but whether due to single or multiple allelic differences has not yet been determined. The possible role of sex-linked genes in the response to selection is considered.
