aPresent data set; bData taken from Haston & Tsui 2003, from the Hospital for Sick Children.

cP-values obtained by standard Pearson's χ2 test comparing observed values to expected 1:2:1 ratio (B6/B6:B6/BALB:BALB/BALB) of genotypes, (except for 1:1 X chromosome genotypes of male mice). B6 = C57BL/6J, BALB = BALB/cJ.

dDXMit16 genotype is B6 or BALB in male mice.
