N normal phenotype
embryo
• authors state that the defects similar to those seen in homozygous mice are present in heterozygotes when one parent is homozygous and the other heterozygous for the null allele

reproductive system
• maternal inheritance of the null allele is increased
• at E10.5, mice carrying a maternal copy of the null allele were more common than those carrying a maternal wild-type copy
• transmission rations of wild-type to null allele are 31% to 54% at E10.5 and 19% to 81% during ovulation
