A single nucleotide polymorphism in exon 3 of the myostatin gene in different breeds of domestic pigeon (Columba livia var. domestica) 32
myostatin polymorphism synonymous mutation muscle growth
2015/4/17
Myostatin is considered to be one of the most powerful negative regulators of muscle growth. The lack of a functional myostatin or its mutation can result in uncommon musculature like “double-muscling...
