amorphic allele - molecular evidence
Excision of the Mi{ET1}abbaMB03490 element resulting in the tnΔB deletion allele.
lethal (with Df(2R)Exel6068)
lethal (with tn1)
visible | pupal stage (with tn1)
tn1/tnΔB pupae are thin and long.
A large proportion of tn1/tnΔB and Df(2R)Exel6068/tnΔB animals die during embryogenesis; either no or very low numbers are lost during larval stages; animals that survive the larval stages die as pupae.
