Sex-linked markers. Display of a permuted dataset in which multiple sex-linked markers have been altered to be scored homozygous instead of hemizygous. Multiple individuals report 'nil from sire' errors (red upper hexagon). All of the affected individuals are in fact male in this case, and cannot inherit a sex-linked allele from their father. This information is lacking from the interface.
