| Abstract: | The recent advances in molecular genetic marker and major genes of meat quality traits for pig and chicken were reviewed in this article. The results showed that 60 QTLs were detected at the chromosome level for meat quality traits on chromosome 1, 2, 4, 5, 6, 7, 8, 10, 11, 12, 13, 14, 15, 17, 18 and X , of which 9 and 1 QTLs were significant at the genome-wise level of 5% and 1% respectively. There were 20 major genes affecting meat quality traits, they include Halothane gene, RN gene and some major genes affecting the lean meat content, the backfat thickness and the intramuscular fat content, of which the Halothane gene and RN gene were widely recognized, and the rest genes should be further examined. |
