Segregation analyses were applied to data from an experimental sheep flock to investigate the presence of a major gene affecting litter size. The data set contained 14 years of litter size data, with up to five parities per ewe, from Cheviot sheep ca

A flock of Cheviot ewes carrying the Thoka gene for fecundity was established in southern Scotland through the importation of frozen semen from two Icelandic rams. Ewes considered to be probable carriers of the Thoka gene were identified on the basis

A digital-image-processing algorithm is described for automatically measuring the diameters of cashmere-goat fibres from microscope images. A correction factor is used to remove bias when fibres are out of focus. Diameters are estimated to within a s
