    Avoiding Lethal Whites

    My trainer today was talking to me today about Lethal White foals during a group lesson. So I know what they look like and that they die soon after birth, but I was wondering what causes foals to be Lethal White and how you can avoid it when breeding.

    Testing for the frame overo gene (also known as the OLWS or LWOS gene) can prevent a lethal white foal.

    Lethal whites (or LWOS/OLWS) foals are created when you breed two horses who are positive for frame together. When you do this, you have a 25% chance of creating a lethal white foal.

    Because white patterns can hide (one member has a mare with a small star as her only white, yet she tested positive for frame), it's important to test any horse you suspect of carrying frame before breeding.

    I'd go a step farther and say to test ANY horse, not just ones you suspect, if it is a breed that has shown to carry LWO. If either horse tests negative, then you can breed without fear of a lethal white foal.
