Strain is homozygous viable due to redundancy of act- and act-3 genes. AT 15C, all embyros produced by homozygous mothers hatch; at 26C, 88% of embryos hatch.

This removes 163/376 amino acids of the act-2 sequence (calculated with ATG methionine included). Sequence of deletion is (text inside of slashes is deleted, with 5' and 3' sequences shown): (exon#2)5'....gtgaaatcgtgcgtgacatc/aaggagaagctttgtt........ ...tggatagacattggtgt/gcgcactccttctggat.....3'(872 nucleotides from stop codon).
