D. melanogaster
FlyBase ID

Sequence coordinates
Member of large scale dataset(s)

Set of Y;3 translocation stocks designed to allow generation of aneuploid animal by crossing two members of the set with breakpoints flanking the region of interest. For most regions, animals carrying both the duplication and the deficiency of the region between the autosomal breakpoints can be recovered and unambiguously identified.

In combination with other aberrations

Lethal in combination with Df(3R)L16. This lethality is partially rescued by a single copy of OsbptAa. Although T(Y;3)B197/Df(3R)L16 is lethal, this combination no longer shows the cell cycle arrest phenotype described in FBrf0049898, presumably due to the accumulation of modifiers. It is therefore not possible to ascertain whether the cell cycle aspect of the phenotype of T(Y;3)B197/Df(3R)L16 animals is due to lack of Osbp.

Heterozygotes with In(YLS)B1 are fertile and heterozygotes with In(YL)B2 or In(YL)B3 are sterile.

T(Y;3)B197/Df(1)bb158 male sterile

NOT in combination with other aberrations

Chromosome is male sterile in the absence of an extra Y chromosome.

X/T(Y;3) male sterile
