Homozygous question just out of curiousity
 
This is just a question out of curiousity not about breeding at all. I'm just wondering is all. If a foal's dam is Homozygous for the tobiano gene but the father is Heterozygous for tobiano what if any chance will the foal be Homozygous tobiano?

You have a 50% chance of the foal being homozygous for tobiano.

Thanks! Just something i've been wondering about.

Yup, as ever, ND is correct :-)

Just wanted to add that being homozygous for tobiano is not a guarantee for colour :-)

Now that I knew. Thanks for the reply. :wink: I've learned a lot about horses colors and genetics from this forum and books.
