Purebred are those animals that have been bred-up to purebred status as a result of using full blood animals to cross with an animal of another breed. Artificial breeding via artificial insemination or embryo transfer is often used in sheep and cattle breeding to quickly expand, or improve purebred herds.
A pedigree chart is a diagram that shows the occurrence of certain traits through different generations of a family, [1] [2] most commonly for humans, show dogs, and race horses. [ citation needed ] Definition
In this pedigree chart, G is the progeny of C and F, and C is the biological uncle of F. To find the coefficient of inbreeding of G, first locate a loop that leads from G to the common ancestor through one parent and back down to the other parent without going through the same individual twice. There are only two such loops in this chart, as ...
Animal breeding is a branch of animal science that addresses the evaluation (using best linear unbiased prediction and other methods) of the genetic value (estimated breeding value, EBV) of livestock. Selecting for breeding animals with superior EBV in growth rate, egg, meat, milk, or wool production, or with other desirable traits has ...
(It is conventional in genetics to use capital letters to indicate dominant alleles and lower-case letters to indicate recessive alleles.) The probability of an individual offspring's having the genotype BB is 25%, Bb is 50%, and bb is 25%. The ratio of the phenotypes is 3:1, typical for a monohybrid cross. When assessing phenotype from this ...
Some registries, such as American Kennel Club, may include a record of the absence of certain genetic defects, known as a certification, in an individual dog's record. For example, the German Shepherd Dog national breed club in Germany recognizes that hip dysplasia is a genetic defect for dogs of this breed. Accordingly, it requires all dogs to ...
Genotype can also be used to refer to the alleles or variants an individual carries in a particular gene or genetic location. [2] The number of alleles an individual can have in a specific gene depends on the number of copies of each chromosome found in that species, also referred to as ploidy .
Braunvieh, a dairy breed [1] with high milk production and little milk fat. A breed is a specific group of breedable domestic animals having homogeneous smell (), homogeneous behavior, and/or other characteristics that distinguish it from other organisms of the same species.
