breeding value


Also found in: Acronyms.

breeding value

the (economic) worth of an individual's GENOTYPE, as judged by the average performance of its offspring. From the size of the breeding value it is possible to choose suitable parents for future crosses.

See PEDIGREE ANALYSIS.

breeding value

the sum of gene effects of a breeding animal as measured by the performance of its progeny.

aggregate breeding value
see true breeding value (below).
estimated breeding value
an estimate of the ability of an individual to produce superior offspring; based on one or more measurements of performance, using phenotypic values, taken on the animal itself or, more commonly, on a number of its relatives.
true breeding value
genetic merit of an individual which can be conceptually defined as twice the average deviation of its offspring from the population mean when mated randomly to an infinite population.
true overall breeding value
the true, overall breeding value arrived at by the addition of the true breeding values for each selection objective with each true breeding value multiplied by the relevant net economic value.
