The diversity of animal genetic resources includes diversity at species, breed and within-breed level. Known are currently 8,800 different breeds of birds and mammals within 38 species used for food and agriculture. [1] The main animal species used for food and agriculture production are cattle, sheep, goats, chickens and pigs. In the livestock ...
The BLUPF90 family of programs is a statistical software package used in quantitative genetics for animal and plant breeding. [1] [2] It can fit mixed models using restricted maximum likelihood as well as Gibbs sampling to estimate variance components, and predict breeding values via best linear unbiased prediction (BLUP).
Expected progeny differences (EPD) are an evaluation of an animal’s genetic worth as a parent. They are based on animal models which combine all information known about an individual and its relatives to create a genetic profile of the animal’s merits. These profiles are then compared to other individuals of the same breed.
Roan is a coat color found in many animals, including horses, cattle, antelope, cats and dogs. It is defined generally as an even mixture of white and pigmented hairs that do not "gray out" or fade as the animal ages. [1] There are a variety of genetic conditions which produce the colors described as "roan" in various species. Bay Roan with ...
"Horse Color Calculator" Archived 2016-12-12 at the Wayback Machine From Animal Genetics Incorporated. This creates the possible coat coloring of the offspring from the imputed color of sire and dam. "Horse Genome Project" A quick summary of horse color genetics.
Two fundamental calculations are central to population genetics: allele frequencies and genotype frequencies. [1] Genotype frequency in a population is the number of individuals with a given genotype divided by the total number of individuals in the population. [ 2 ]
In population genetics, the Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences.
