INBREED Procedure


The INBREED procedure calculates the covariance or inbreeding coefficients for a pedigree. PROC INBREED is unique in that it handles very large populations. The following are highlights of the procedure's features:

  • supports two modes of operation:
    • Mode 1: carries out analysis on the assumption that all the individuals belong to the same generation
    • Mode 2: divides the population into nonoverlapping generations and analyzes each generation separately, assuming that the parents of individuals in the current generation are defined in the previous generation.
  • computes averages of the covariance or inbreeding coefficients within sex categories if the sex of individuals is known
  • performs BY group processing, which enables you to obtain separate analyses on grouped observations
  • creates a SAS data set that corresponds to any output table
