progeny test

progeny test

a method by which the genetic capabilities of an organism can be established by examining the performance of its progeny. For example, the ‘milk-yield’ genes of a bull can be estimated by measuring the milk productivity of its daughters.

It is important to point out that the National Breeding Program of Dairy Gyr (PNMGL) began in 1985 with the progeny test; however, only in 1994 the first genetic evaluation was carried out, based on the dairy control data of the heifers of the first batch of the test bulls of ABCGIL and the ABCZ database.
To make even greater genetic progress, he added, Hampshire Down breeders have agreed to join forces with the other four major terminal breeds in AHDB Beef and Lamb's pioneering progeny test, the RamCompare project.

The initial development of YY-males requires feminization of XY fry during their sexually undifferentiated stage and the identification of these newly created "sex-reversed females" (females XY) through a progeny test (Vera-Cruz et al., 1996; Mair et al., 1997).
