Abstract excerpt
BACKGROUND: In cattle, base color is assumed to depend on the enzymatic activity specified by the MC1R locus, i.e. the extension locus, with alleles coding for black (E(D)), red (e), and wild-type (E+). In most mammals, these alleles are presumed to follow the dominance model of E(D) > E+ > e, although exceptions are found. In Bos indicus x Bos taurus F2 cattle, some E(D)E+ heterozygotes are discordant with the...
