Phenotypic Data
Phenotypic Class
Phenotype Manifest In
Detailed Description
Statement
Reference

33% of the legs of the legs of BM2 hemizygous males have a weak fusion between the fourth and fifth tarsal segments, with the joint not properly differentiated.

Central folding in the leg discs occurs normally in In(1)BM2 mutants. Tarsal segments 3-5 are partially fused with each other in In(1)BM2/Df(1)B flies.

Homozygotes have a slight indentation at the anterior edge of the eye.

Phenotype less extreme than that of B1. RK2A.

Additional Comments
Genetic Interactions
Statement
Reference

The tarsal segment phenotype of BM2 hemizygous males is enhanced by apUGO35/+: in the resulting flies tarsal segments 4 and 5 are shorter and are fused in 61% of the legs.
