Insertion of P{SUPor-P} into Scim24.
mitosis & nuclear chromosome
Dominantly decreases transmission of Dp(1;f)J21A to offspring to 19%. Recessive lethality acts in the third larval instar stage. Larval neuroblast squashes reveal a lower than normal mitotic index and some mitotic figures exhibit aneuploidy and/or decondensed chromosomes. Many nuclei appear disintegrated, similar to the phenotype of Scim251.
