![]() ![]() It is known that chromosomal anomalies are one of the principal genetic causes of infertility in horses. The study team found that sexual chimerism in PREs is not linked to infertility, despite the unusual genetic configuration. The research, carried out at the universities of Seville and Cordova, focused on the recent breeding of purebred Spanish horses, the Pura Raza Español (PRE) breed. An individual carries two distinct genetic make-ups. Chimeras may also show a distinctive bi-colored coat.Ī study conducted at a Spanish university has cast a spotlight on the rarity among chimerism horses. The DNA test for male and dandruff samples can reveal two people, and the blood test will tell whether the specimen is a chimera. Whereas sometimes, as this phenomenon can be found in dogs and cattle, this distinctive coat is hereditary. This striking coat pattern is more typical for example, the twin embryos were bay and chestnut. Sometimes, chimeras have differentiated twigs in the coat. In cats and even humans, chimerism was also known Characteristics of Chimera Horse When the embryo grows naturally, body parts, tissues, etc., are made up of various DNA, resulting in a ”genetic mosaic” organism whose body comprises a combination of cells of two different genotypes. ![]() A chimera is a horse formed from two genetically-different DNA forms, which occurs when non-identical twin embryos merge into one at an early stage of development. ![]()
