this is the stud I'm confused his genes are not lethal I thought
Magical Texas Tea RS

I think its the interaction of his Kit^m and her Kit^sb1 but someone who is more confident in their genetics may tell you otherwise and provide you a more thorough explanation. There's a table that explains the lethality of different pairings of white genes but I don't know exactly where it is.

The risky gene combination is the KitM KitW2, which is lethal if the foal has large or extensive white factor, if I am reading the chart right. You have been able to get live foals before because there is only a 25% chance that a foal of these horses will inherit both of those genes, and even if it does, the chances of high white factor are fairly low since the parents are light and minimal. However, the possibility does exist, and this foal had the bad luck to get the lethal combination.

It's easy to forget that there is a large amount of variability built into almost everything in this game. Just as in real life, there's a considerable uncertainty factor that comes into play. It can be frustrating when the uncertainty pushes some aspect into a range that we really wish it would not, and sometimes those are the times that get fixed into our memories.

On the other hand, there really are times when the variability swings the other way. My prime example is the C papered ordinary create stallion that I put into a pasture with a bunch of ordinary create mares. That was back shortly after pastures were introduced. At this distance in time, I no longer remember if the mares got 30 days in pasture before the first breeding, but that stallion gave me 4 A papered sons in the first two seasons, and 3 of them were in the first year. I don't believe that I swapped out any of the mares for the second, because I liked to leave them there until they had 3 foals and I could paper them.

hum yea I don't normally breed W2 I only breed those two mares in hopes for the foal to get the sabino 1 gene not the W2 so I forget about how lethal W2 can be and I did not know W2 and kitm were bad together with a high white factor and if I would have known they can be lethal I wouldn't have bred that pair because my stud with kitm throws a lot of foals with high white factor

I have a smaller farm so what I do whenever I have new horses come into season I have a file for them listing the horse that they are safe with. I choose their mate from their personal list it saves me from continually having to look up the chart.
