Heterozygotes are WT and segregate dead eggs, DpyUncs and WT. lin-26(mc15) is a molecular null due to a deletion of most of lin-26 coding sequence.

Heterozygotes are WT and segregate WT, Uncs and dead eggs and larvae with severe body morphology defects that do not develop beyond the L2 stage. A few very rare mc44 larvae reach adulthood but they become sterile. mc 44 is a deletion affecting the downstream transcription unit of vab-10 named vab-10b. Fails to complement the vab-10 null reference allele vab-10(h1356), but complements the vab-10a alleles vab-10a(e698) and vab-10a(ju281).

Heterozygotes are WT and segregate WT, DpyUnc and dead eggs (mc1 homozygotes). mc1 is a strong loss of function mutation, but probably not null. mc1 is an embryonic lethal mutation with degeneration of hypodermal cells.
