do you mean i should change the design? because i dont want to 

or would it be more like the splash gene is in the horse and can be passed on but the horse itself is still solid (almost) chestnut ? im sorry this whole genetics is a whole new world to me i literally know 0 about it oTL
how accurate do i actually have to be on es haha i had an idea of searching for real life akhal tekes online and making them dam and sire to my horse so im thinking what best coats they should be to make my horse comprehendible? pshh i dont know anymore oTL
thats amazing! is it really like that in real life? wow ! my dream horse could really be out there if so haha 
edit: i just realised i quoted you guys wrong oTL sorry im on my phone
