Adults homozygous for trblunspecified can survive to adulthood. Loss of homozygotes does not appear to occur at any specific stage but throughout all developmental stages. Homozygous adults appear normal, except that females are infertile, laying very few eggs; these look normal but are rarely fertilised. No gross abnormalities are seen in ovaries.
trblunspecified/trbl[+] is a suppressor of visible phenotype of Myt1GMR.PP, Wee1GMR.PP
trblunspecified/trbl[+] is a suppressor of eye phenotype of Myt1GMR.PP, Wee1GMR.PP
The eye phenotype caused by two copies of Myt1GMR.PP combined with a single copy of weeGMR.PP is partially suppressed by removal of one copy of trbl.
In double mutant stgunspecified trblunspecified embryos no mitosis takes place during gastrulation and the ventral furrow forms as in wild-type.
