mortality/aging
embryonic lethality before implantation, complete penetrance ( J:107240 )
• no homozygous embryos are found between E10.5 and E18.5; only 2/90 embryos isolated at E2.5 to 3.5 were homozygous
• no embryos examined at the 8-cell (blastocyst) stage are homozygous

Background		 involves: 129S1/Sv * 129X1/SvJ * CD-1

♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
reproductive system
transmission ratio distortion ( J:107240 )
• ratio of heterozygotes to wild-type offspring heavily favors heterozygotes; instead of 1:2 expected hets to wild-type, 23 wild-type to 176 heterosygotes is observed
• when mutant allele is maternally-derived, overrepresentation of heterozygotes is more pronounced than when mutant allele is transmitted by the male
