Surprisingly, however, the cellular and molecular programs employed to create similar organs are not evolutionarily conserved.[uncertain][VHOG] FBbt:00004858 FMA xref is a 'general anatomical term' FMA:18250 GAID:368 HAO:0000379 MA:0002420 MESH:D006066 OpenCyc:Mx4rwQvdiZwpEbGdrcN5Y29ycA Reproductive organ that produces and releases eggs (ovary) or sperm (testis).
