What is the tobiano gene?

Tobiano is a spotted color pattern commonly seen in pinto horses, produced by a dominant gene. The tobiano gene produces white-haired, pink-skinned patches on a base coat color.

Can you breed a tobiano to an overo?

A tobiano bred to an overo can result in a horse that has both tobiano and overo color patterns and are called Tob/overo or Tovero. The overo gene is not related to the tobiano gene and the overo gene does not effect the expression of the tobiano gene.

Is a tobiano a pinto?

Tobiano: The most common type of pinto, tobiano is a spotting pattern characterized by rounded markings with white legs and white across the back between the withers and the dock of the tail, usually arranged in a roughly vertical pattern and more white than dark, though the ideal is a 50-50 distribution, with the head …

What colors make a buckskin horse?

Buckskin horses have a coat color of tan or gold with a black mane, tail, and lower legs. In addition to the coloring, a genuine buckskin is also a hardy horse.

Is the crème gene dominant or recessive?

incomplete dominant allele
The cream gene (CCr) is an incomplete dominant allele with a distinct dosage effect. The DNA sequence responsible for the cream colors is the cream allele, which is at a specific locus on the MATP gene.

Is my horse tobiano or overo?

An overo horse has a mostly solid-colored body with white patches, which can be quite large, that do not cross the spine at any point. An overo horse’s mane and tail usually are dark, while a tobiano may have white mixed in with the mane and tail color.

Is a tobiano horse homozygous for white?

For breeders interested in producing tobiano foals, a horse that is homozygous for tobiano is desirable in a breeding program. Unlike other white spotting patterns caused by specific changes in DNA sequence of the genes, tobiano is associated with a large chromosome inversion that likely affects the function of the pigmentation gene KIT.

What is the dominant allele for Tobiano?

The tobiano gene has two alternative states (alleles). The dominant allele, TO, produces the tobiano pattern and the recessive allele, called “N” by VGL but “to” by others, is non-tobiano. A horse that is homozygous for tobiano, symbolized as (TO/TO), will always produce offspring that are tobiano regardless of the mate.

What is a tobiano horse pattern?

The Tobiano horse pattern is characterized by large white areas across the topline that extend downward in a vertical pattern, usually leaving the head, chest, and flanks colored. The edges of the white spots are generally regular and smooth.

Can paint horses produce tobiano offspring?

They can, nevertheless, produce tobiano offspring as reliably as any other horse with the tobiano gene. It has been suggested that paint horses with extensive white are usually a combination of patterns, and this may well be the case.
