Somatic gonadal precursors (SGPs) are specified normally, but primordial germ cells are absent in embryos derived from oskCE4
females. The SGPs compact into spherical 'gonads' even in the absence of the germ cells.
In embryos laid by osk8
mothers, compaction of somatic gonadal precursors in parasegment 10 (part of embryonic gonadal mesoderm) occurs normally, even though these embryos lack germ cells.
The gonadal mesoderm coalesces normally in embryos derived from osk8
females, even though the embryos lack germ cells.
