Detailed Description
Statement
Reference

Rbfox1e03440/Df(3L)ED4457 results in female sterility and a germ cell tumor phenotype (accumulation of germline cysts that fail to differentiate beyond early stages).

Homozygous germline clones fail to differentiate properly and become tumorous. Egg chambers in which the entire follicle cell layer is homozygous appear normal through the early stages of oogenesis.

Germline cysts from A2bp1KG06463/A2bp1e03440 ovaries show germ cell counting defects at high penetrance and a mildly tumorous phenotype at low penetrance.

A2bp1f02600/A2bp1e03440 females are weakly fertile, but nearly all cysts cells undergo an extra mitotic division so that the egg chambers contain 32 germline cells.
