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.
