Friesian Cross

Parentage/Genetic Marker Report

This DNA-based parentage test uses microsatellite marker analysis to compare the DNA profile of an offspring to the profiles of possible parents.

Horse Embryo Pre-Implantation Genetic Diagnosis

Pre-implantation genetic diagnosis (PGD) is a procedure used to screen embryos recovered after uterine flush to determine sex and genetic traits through DNA testing prior to implantation in the uterus.

Friesian Horse Hydrocephalus

Hydrocephalus is an inherited condition in Friesian and Friesian crosses characterized by excessive accumulation of fluid in the brain that results in severe cranial distension.

Friesian Horse Dwarfism

Dwarfism in Friesians is an inherited disorder characterized by a disproportionate growth with reduced bone length of limbs and ribs while the size of the head and length of the back are normal.

Tobiano

Tobiano is a white spotting pattern characterized by white on the body that crosses the topline.

Red Factor

The extension gene, or red factor, determines whether a horse will have a chestnut base coat color or a black or bay base coat color.

Gray

The gray gene causes progressive depigmentation of the hair, often resulting in a color that is almost completely white by 6-8 years of age.

Dominant White Mutations – W5, W10, W20, and W22

Dominant white is a variable white spotting pattern caused by many different mutations in the KIT gene. The VGL tests for the four most common mutations known as W5, W10, W20, and W22. Homozygosity for W5, W10, or W22 is thought to be non-viable.

Cream

Cream is a dilution that causes the palomino, buckskin, smoky black, cremello, perlino, and smoky cream coat colors.

Agouti (Bay/Black)

The agouti gene controls the distribution of black pigment, and determines whether a horse will have a bay or black base coat color.
