A bull, for example, cannot be assessed for milk production, however, the performance of its female offspring can be used to determine the use of the animal for future crosses. A progeny test is performed by mating the male with a number of females to produce many progenies in a different environment and over a long time period involving ...
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 ...
G is the progeny of C and F, and C is the biological uncle of F. 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 ...
In animal breeding, the progeny of a cross between breeds of the same species is called a crossbreed, ... Also DNA testing and genetic screening.
Only those breeding and selection methods are suitable for a crop which does not interfere with its natural state or ensure the maintenance of such a state. It is due to such reasons that imposition of self-fertilization on cross-pollinating crops leads to drastic reduction in their performance.
A well-designed mating increases the probability of the offspring's success, although many other factors also come into play. Many thoroughbred breeding theories are implemented from other animal breeding stock practices, such as the use of inbreeding to "fix a type". Some breeding theories are qualitative, relying on judgement.
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.
In conducting a monohybrid cross, Mendel initiated the experiment with a pair of pea plants exhibiting contrasting traits, one being tall and the other dwarf. Through cross-pollination, the resulting offspring plants manifested the tall trait. These first-generation hybrids were termed F1, with their offspring referred to as Filial or F1 progeny.
