Homozygotes die at room temperature, though unclear whether recessive lethality due to l(2)DTS911 or other mutation.
Dominant temperature sensitive lethality is incompletely penetrant. Escapers of lethality show delayed eclosion.
The temperature-sensitive period of heterozygotes appears to be near the end of embryogenesis.
l(2)DTS911 is one of the 11 DTSs that mapped between dp and b reported in FBrf0020925.
