Backcross and F2 analyses have been carried out to determine the genetic basis of inheritance of three myosin light chain-1 variants present in the fast white muscle fibers of the domestic chicken. Two of the variants (types I and II) were described previously [Rushbrook, J. I., Yuan, A. I., and Stracher, A. (1982). Muscle Nerve 5:505], while the existence of the third (type III) is reported here. The results are consistent with an autosomal and allelic origin for the variants. A test linkage backcross to the muscular dystrophy gene am was found to be negative. This is the twelfth negative linkage result for the am gene.
