RECENT INFORMATON OF POPULATION AND QUANT ITATIVE GENETICS IN FARM ANIMAL BREEDING

The paper defines a position of population and quantitative genetics i n the breeding process while current fields in which population and qu antitative genetics is engaged are reviewed with respect to farm anima l breeding and the present knowledge, tools used and trend of developm ent are outlined. The fields of concern are as follows: genetic modell ing, economic values of commercial characteristics, determination of g enetic parameters, choice of new selection criteria, breeding value es timate, marker supported selection, selection principles, genetic gain , determination of crossing effects, optimization of selection and hyb ridization programs.
