loss of function allele
lethal | recessive
lethal - all die before end of larval stage
some die during larval stage
larval abdominal segment 1
larval abdominal segment 2
larval abdominal segment 3
larval abdominal segment 4
larval abdominal segment 5
larval abdominal segment 6
larval abdominal segment 7
larval mesothoracic segment
larval metathoracic segment
larval prothoracic segment
Homozygotes die during the embryonic or first larval instar stages.
Homeotic transformation of the prothoracic through the seventh abdominal segments to the eighth abdominal state (Breen, Dev Biol 118:442 ).
Transformation of A6 and A7 toward A8.
enhancer of Mcp
ScmD2 is an enhancer of visible | dominant | homeotic phenotype of Pc3
ScmD2, ph-p409 has partially lethal phenotype
ScmD2 is a suppressor of phenotype of z1
Dominantly enhances the homeotic phenotypes of Pc3/+ adults. ph-p409 males that are also heterozygous for ScmD2 show partial lethality.
Weak derepression of en expression.
