Hi! Thanks for the vote! Heres one from us! In today's and until I run out (hehe) we are going over the Paint horse COLORS! You probably already know some or ALL of them but some I didn't even know about! Truely!! Here is a little about the TABIANO!
~~The TABIANO~~
Tobianos have dark heads, patterns of white that usually cross the top line, white hooves, and white on the legs above the knees and hocks. The edges of the spots are smooth and sometimes shadowed. Some have "ink spots" inside the white areas. A single dominant genetic trait, the tobiano allele, causes tobiano markings. An allele is a variation on a gene. If a horse carries this allele, it will always show tobiano or tovero markings. If it has only one copy of the allele (heterozygous), it has only a 50% chance of passing on this allele. If you breed heterozygous tobianos to each other, on the average one out of every four foals will be solid-colored. If a horse carries two copies of the tobiano allele (homozygous), all offspring will be tobianos or toveros, even if the other parent was a solid colored horse. You can be almost certain that a horse is homozygous if it has "paw prints" or "bear paws." These are areas of roan within the white spots. Blood tests can also reveal whether a horse is homozygous.A horse that is genetically tobiano will sometimes have minimal markings, not enough to register except as breeding stock. In these cases, the horse will have white hooves and stockings, yet a face with no white. A minimally marked tobiano is as likely to have tobiano offspring as are those with more white. |
