To analyze X-linked markers, we fit an extra variance components <math> {{\sigma_g}_X}^2 </math> for chromosome X kinship <math> \boldsymbol{K_x} </math>,

To analyze X-linked markers, we fit an extra variance components <math> {{\sigma_g}_X}^2 </math>, to model the variance explained by chromosome X. A kinship for chromosome X, <math> \boldsymbol{K_x} </math>, can be estimated either from a pedigree, or from genotypes of marker from chromosome X.
