Sentences with phrase «in medaka»

When germ cells are removed in medaka, XX (female) fish show female - to - male sex reversal, while XY (male) fish with excessive germ cells, which is usually associated with egg production, exhibit male - to - female sex reversal.

Germ cells, irrespective of the sexual fate (to become sperm or eggs), have the potential to feminize the body in medaka.
