the present results suggest that x-linked genes in metatherian fibroblasts are subject to the same kind of determinate , paternal allele inactivation , incomplete at some loci , described previously for x-linked genes in adult tissues and that the pattern of paternal x-linked gene expression in these cells is independent of the patterns in the tissues from which the fibroblasts are derived .
