reproductive system
transmission ratio distortion ( J:113280 )
• transmission of deficient allele decreases with each generation in backcrosses to C57BL/6 such that by F4, there is only one male heterozygote out of 37 offspring
• background sensitivity when an F3 heterozygote is backcrossed to 129/Sv, the mutant allele shows 54% transmission
