I don’t know if sw2/sw2 is lethal.

All the kit genes have the potential to be lethal but, for most, the chance is really small. As far as I understand it, and I could be wrong, is that we can think of it as a math problem. Let us pretend that a horse dies of lethal white if it reaches x (100) number of kit death points. So then think that each kit has a chance of having a number from 1-50– W1 and w10 being the highest and things like R being very low. Then assume that white factor is a multiplier. So a w1/w1 starts at 100 points, which could be death, so you can’t have much of a multiplier (white factor.)

This is just the way to think about it but the numbers are wrong. All my w1/w1 have no white factor. My w3/w1 have minimal to light. White factor is the true enemy in lethal white.

The kit genes cause death differently than O. The kit genes die during pregnancy while O is when they live but the intestines haven’t formed so they die badly. O/O is always fatal, regardless of white factor.

I don’t know anything about the splash genes— @thebluemoors ?


Winters Vegas One W1

Splash 2 is caused by a different gene from normal splash (PAX3). It is more aggressive and results in bigger white markings. It is homozygous lethal and lethal with SW3.

Copied from the Splash 2 description on the Gene Modification page. That's probably where you saw it SmoothRiverFarm. :)

That chart is the KIT lethality chart only. It does not have any other genes.

Cool, thanks, guys!
