Sex determination based on coverage of nuclear SNPs in the '1240k′ array using putatively deaminated reads

Sample ID	Material	Nyo (# bases covered on Y chromosome)	Nxo (# bases covered on X chromosome)	Nautoo (# bases covered on autosomal chromosomes)	Ny expected (targets on Y chromosome)	Nx expected (targets on X chromosome)	Nauto expected (targets on autosomal chromosomes)	X-ratio (Nxo/Nautoo)/(Nxe/Nautoe)	Y-ratio (Nyo/Nautoo)/(Nye/Nautoe)
C7/675	Human tooth - left udm1	49	1,312	45,032	32,670	49,704	1,150,639	0.674	0.038

A Y-ratio <0.05 indicates a female and >0.2 indicates a male.
