  • Screening method for homozygous genotype agouti hair color rabbits
    Patent number: 12173373
    Abstract: The invention provides a selecting method for domestic rabbits with a agouti/Belgian hair color based on homozygous genotype selection. The purification method is applicable to purification of various domestic rabbits with the agouti/Belgian hair color. The method includes the following steps: firstly, selecting the domestic rabbits with a hair color phenotype which is the agouti/Belgian hair color; then detecting an ASIP gene, a MC1R gene and a TYR gene at the same time by utilizing a first primer set, a second primer set and a third primer set; screening the domestic rabbits with genotypes of AA (corresponding to the ASIP gene), EE (corresponding to the MC1R gene) and CC (corresponding to the TYR gene). The domestic rabbits with the genotype of AAEECC, which are obtained by the screening method of the invention, are agouti/Belgian hair color homozygotes and the recessive white gene is eliminated.
