1 MFD—mean fibre diameter; FDSD—fibre diameter standard deviation; CVFD—coefficient of variation of fibre diameter; MFC—mean fibre curvature. 2 Among the 225 sheep (excluding those carrying the rare variant E), variant A was absent in 90 and present in 135 animals; variant B was absent in 147 and present in 78 animals; variant C was absent in 113 and present in 112 animals; variant D was absent in 185 and present in 40 animals; and variant F was absent in 187 and present in 38 animals. 3 Predicted means and standard errors derived from GLMs, with p < 0.05 being presented in bold.
