In the past 20 y ears, sequencin g te chnolog ies have le d t o easy access t o geno mic data fro m no nmodel o r ganism s in a l l biolog ica l rea lm s.

Recep t or-Mediat ed Ovary Transd uctio n o f Car g o (ReM OT Control) acts as a n a lternat ive to embry- o nic micro inj e ct ions, which re quire expen siv e equi p m ent an d exten siv e h and s-on training .
