Killer Chromosomes — Warren Murphy; Richard Sapir

THE LADY OR THE TIGER?
What happens when a lady scientist discovers a "key" to the manipulation of genetic patterns that keep different species from intermingling?

The lady becomes a tiger -- of the man-eating variety. She is wild, beautiful, and deadly. And she soon decides that she must share her sinister secret with other women. The lovely killer genes multiply geometrically ... and so does the fatality rate. The country becomes littered with chewed-up bodies. All men.

Enter Remo and Chiun -- The Destroyer -- the only weapon against this carnivorous cutie. Handsome Remo, fast on the chase becomes her prisoner -- her love slave. Conspiracy and criminality fall into Remo's usual area of operation. Genetic warfare and animalistic passions are something else again. Especially when the enemy looks like a Playboy centerfold!

So, as Remo is about to choose between going down in flames or up in smoke, Chiun sees a way to preserve the integrity of man's chromosomes, and stay alive....something to do with an ancient Korean proverb about knowing which tale of the tiger to take!
