mom-2(or77) is a recessive, non-conditional maternal-effect embryonic lethal. Weak allele of mom-2/Wnt (splice acceptor mutation in last exon (exon6). 8% of mutant embryos lack gut. Heterozygotes are Unc.

mom-2(or85) is a recessive, non-conditional maternal-effect embryonic lethal. Strong allele; missense mutation near N-terminus: L77P. 85% of mutant embryos lack gut. Heterozygotes are Unc. [NOTE: (08-27-2014) We have been informed that the mutation carried in this strain is the same molecular lesion as or77. We are working to determine if or85 and or77 are in fact the same lesion or if an incorrect genotype was provided for the strain.]
