Abstract—The present research was aimed at presenting a genetic analysis of the associations between single nucleotide polymorphisms of MYOD1 and meat quality traits in commercial lines of Pakistani cattle breeds. The breeds were Red Sindhi cattle (RS), Thari cattle (TR), Sahiwali cattle (SW), Bhagnari cattle (BN) and Cholistani cattle (Cl). The results of the Allelic frequencies and Polymorphism Information Content showed a medium diversity. Least Square analysis for the novel mutation c.679G>A is significantly associated (P>0.05) with Back fat thickness (BFT) and Marbling (MB) but did not show a significant association with other traits such as Eye muscle area (EMA), Water holding Capacity (WHC), and meat tenderness (MT). Animal Geneticians and breeders consider both of these traits as the key traits for determining the meat quality in animals. This research will be helpful to furthermore improve the meat quality in Pakistani cattle breeds by using the marker assisted technology.
