YY Technology

YY Technology

Instead of breeding females (XX) with regular male tilapia (XY), which will create both male and female offspring, we create (YY) with temperature. Breeding a YY male with a female results in a 98% male population, that always works.

Breeding with XY males:

Tilapia can be genetically:

Because the male provides the Y-chromosome that will determine the offspring’s gender, we breed YY males to ensure all male offspring

This creates a 50% chance the offspring will be male.

YY technology creates only males.

NMT™ are produced by crossing a YY male with a normal female (XX) from a separate mixed sex line.

By crossing two different lines for NMT™ production, the NMT™ line itself is never an inbred fish.
