A frame shift mutation (H241fs) resulting from a one base pair deletion in mus101.
lethal - all die before end of larval stage
some die during larval stage
mus101SM is rescued by mus101+t9
mus101SM is not rescued by mus101tB10
mus101SM fails to complement the larval lethality of mus101lcd and fails to complement the mutagen sensitivity of mus101D1.
Arose in: Paternal X chromosome of mus101SM/mei-9 females, the F1 of a cross between wild-type males and mei-9- females.
