gonad | embryonic stage (with pim66.37)
gonadal sheath proper primordium | embryonic stage (with pim66.37)
visceral mesoderm | embryonic stage (with pim66.37)
pim66.37/pim77.45 embryos have fragmented gonads with loosely gathered somatic gonadal precursors. Somatic gonadal precursor specification appears normal.
