Genomic Test

What is the mission statement of Genetic Visions, Inc.?
"To provide cutting edge research with practical applications for the dairy and beef industries to enhance efficiency, accelerate genetic progress, and maximize progeny test results."

What are Genetic Markers?
Genetic Markers are structural differences in DNA that make is possible to identify and link certain genes to specific traits. If these markers can be linked to traits of economic importance, such as production of milk protein in dairy cows, they become very useful in cattle/sire selection.

What is DNA?
DNA (Deoxyribonucleic acid) is a chemical structure that forms chromosomes. A piece of a chromosome that dictates a particular trait is called a gene. Structurally, DNA is a double helix: two strands of genetic material spiraled around each other. Each strand contains a sequence of bases (also called nucleotides). A base is one of four chemicals (adenine, guanine, cytosine and thymine). The two strands of DNA are connected at each base. Each base will only bond with one other base.

What is a chromosome?
A chromosome is a rod like structure of tightly coiled DNA found in the cell nucleus of plants and animals. Chromosomes are normally found in pairs; cattle typically have 30 pairs of chromosomes in every cell. How can DNA technology enhance cattle selection programs? DNA technology directly measures genetic potential of an animal itself, It reveals genetic merit regardless of age or gender and differentiates between animals with the same or similar pedigrees.

Why is DNA testing important?
Producers routinely take risks when choosing young animals to become future parents in their herds. It is not until a considerable investment has been made than an animal proves its worth. DNA testing "screens" animals at a younger age, so you can welcome a superior genetic pool of calves into your breeding program Along with performance pedigrees, genetic marker technology helps stack the odds in your favor. And in today's competitive marketplace, better information means better choices, more genetic gain and increased profit.

What is the benefit of DNA testing for the dairy/beef producer?
Genetic Visions identifies links to specific traits, but more importantly, heir value. By identifying the trait and its value, Genetic Visions "marks" the animal and its value. Producers can choose the animal with the best combination of traits in which they are interested. DNA technology also helps control genetic defects, many of which do not show up until later in the animal's life. These defects may eventually hamper or destroy the animal, but not until after the producer has made a substantial investment. This is a major economic loss that can be avoided if an animal is "pre∑screened" at a young age.

What is Homozygous?
Homozygous means "pure". The prefix "homo" means the same. Therefore a black animal that has two identical letters representing the same trait would be considered Homozygous Black.
