heat sensitive hypomorphic allele - genetic evidence
lethal | recessive | heat sensitive
Homozygous females are 20% viable at 18oC, 60% viable at 25oC and 0% viable at 29oC. Hemizygous females are 15% viable at 18oC and 0% viable at 25oC and 29oC.
Semilethal at high and low temperatures, viability is highest at intermediate temperature.
