birb5/bi12 transheterozygotes lack HS/VS cells and exhibit increased lethality.
birb5/bi13 transheterozygotes lack HS/VS cells and exhibit increased lethality.
birb5/bi15 transheterozygotes lack HS/VS cells and exhibit increased lethality.
Heterozygotes with biomb-1 lack HS- and VS-neurons and display inner chiasm defects, small alterations to the fibre path.
