the man we are buying our colt and mare with foal, from says that they are all three homogenous? i think i may know what it means, but want to be sure. can anyone tell me? thanks,

I think he means Homozygous. This means that their genes are dominant. Meaning that what ever they are bred they will be passed on to their off spring.

Example: A tobiano patterned horse bred to a solid horse and the foal is tobiano there is a good chance that the tobiano patterned horse is homozygous. The only way to know for sure if a horse is homozygous is to have them DNA tested. Some horses are considered homozygous for a certain trait if they pass it on over 95% of the time.

Home this helps

Uh, I thought homozygous meant that the genes were the same?

For example, a the genotype for blue eyes would be "bb", so it would be homozygous. That's because the gene for blue eyes is recessive.

However, the genotype for brown eyes could be either "BB" or "Bb", because the gene for brown eyes is dominanat. So, this would be heterozygous.

Whether the gene is dominant or recessive, it can be passed onto the offspring either way, P8ntCrazy.

Homogenous means the same... uh, genes, maybe? Not quite sure. Check the internet, maybe that will give you a clearer definition.

This might help explain some of it.
