All You Need To Know About Equine DNA Testing
by Eula Clarke
DNA is the blueprint of all living things. It contains information that dictates how they breathe, eat, reproduce and look like. DNA technology has revolutionized how we do things. It enables one to determine parentage, predict the appearance of a phenotype or even a disease present in the parent population to the offspring. This technology is not only available for humans but also for animals such as horses. <A href="http://www.etalondx.com/">Equine DNA testing</A> is used on horses.
Equines may be tested for several reasons including to determine who their parents are. This information is required for breeding purposes. Determining pedigree information through traditional methods such as observation, manual identification and record keeping is inaccurate and yields the unintended offspring. As a result, scientific methods are preferred.
The process of breeding is usually a careful one. The breeder must identify and select only characteristics that are deemed superior depending on the purpose of the horse. They include better performance, endurance and also certain phenotypic appearances. DNA makes an accurate selection possible. It also helps predict the possibility of developing a disease or certain physical characteristics through the use of a profile.
The globe is dotted with numerous animal genetic laboratories where these tests can be carried out. Searching for them online gives a list of several companies located around the world. Most of them have a list of instructions and guidelines on how to collect samples. After samples are collected, they may be sent to the genetic laboratory through the mail from anywhere across the globe.
The tests may vary in costs depending on the type and number of scheduled tests. Once the analysis is complete, the company will send a copy of the results to you. The results are in the form of a chart that the layman may find hard to understand. However, they will call to explain further what the results mean and the implications for the horse.
The horse owner collects the samples. It is not a difficult process but depends on the sample to be collected. Some tests may ask for some strands of hair either from the mane or the tail. Additionally, one may be asked for cheek cells obtained from inside the cheek using a soft cheek brush. A blood sample is drawn using a syringe. Around 3ml is then transferred to an EDTA Vacutainer and mailed to the laboratory.
Once inside the laboratory, the first step is to extract DNA. The hair follicle cells are used in the case of hair, and the cheek and blood cells are separated until the nucleus is obtained. Once extraction is complete, specialized genetic methods are used to produce a profile or genotype of the equine through the use of a standard twelve specific gene marker. From each marker, there are two alleles and one is from each parent.
DNA technology has become important in our lives and also that of other living beings on Earth. Breeders are able to determine parentage of a horse from the tests. However, the sire and the dam have to be registered prior to the test in order to match the genes of the foal.
