Sorry if there are any threads about this, but I couldn't find it.
Is there any thread or site that explains which colour a foal can be, depending on his parent's colour?
You can't get a palomino out of a black horse, can you?
You can if the black horse is hetrozygous for the black gene and carries red so it would be Ee and is bred to an ee (chestnut) carrying a dilute gene or anothe Ee horse that's carrying a dilute gene.
Amm, this sounds a bit complicated to me. I'm totally new to this topic.
I just gave the example, it's not that I'm breeding or something, but I am interested in this colour stuff.
Hetrozygous means not dominate gene? How could I know if some horse is hetrozygous?
Hetrozygous means it carries different alleles (variations of a gene) so in this case the base colour of any horse is red (ee) or black (Ee or EE). Hetrozygous means different (more or less), homozygous means same so a chestnut horse is homozygous for ee but a black can homozyous (EE) or hetrozygous (Ee) as black is dominant to red as red is the recessive gene. You would only know if you genetically tested or bred to a horse that was homozygous for the recessive gene so say you bred your black horse to a chestnut. If your black was homozygous for black it could never produce a chestnut foal but if it was hetrozygous there's a 25% chance it will produce a chestnut foal.
Color Calculator Here's a fun calculator if you want to figure out colour possibilities.
NDAppy is working on a massive explanatory thread/website to explain the basics of colour genetics. I am currently proofreading it and it's looking pretty sweet.
