expected progeny difference (EPD)

the difference in performance to be expected from future progeny of a sire, compared with that expected from future progeny of the average sire in the same population. EPDs are generally expressed either as a plus or minus difference from the population average, reported in the units of measure of the trait.

progeny testing

a test originally based on red cell antigens but increasingly on restriction fragment length polymorphisms (RFLPs), called also DNA fingerprinting. The offspring can have only those blood group antigens possessed by one or both of its parents. Identification of the offspring's antigens makes it possible to exclude some possible sires because they carry antigens not possessed by the subject animal. Similarly, the inheritance of a particular RFLP is directly linked to that found in each parent. Called also parentage determination, parentage exclusion testing.
