Exo70exc13, mtrmexc13 has partially lethal - majority die phenotype
The "exc13" chromosome (which carries the exo70exc13 and mtrmexc13 alleles) shows recessive semi-lethality; less than 50% of the expected number of homozygous adults eclose out of their pupal cases and those that do die within 1-2 days of eclosion.
Associated with: mtrmexc13.
