Mutants are not stress sensitive. Hemizygous males are viable, homozygous females show reduced viability.
Haplo-specific lethal mutation. Survival rate is close to that of wild type.
Haplospecific alleles survive as males or homozygous females, but die in heterozygous combination with a deficiency for the locus.
Separable from: a separable X-linked lethal mutation.
Haplo-specific lethal allele.
