You can specify the MATINGS statement with PROC INBREED to specify selected matings of individuals. Each individual given in individual-list is mated with each individual given in mate-list. You can write multiple mating specifications if you separate them by commas or asterisks. The procedure reports the inbreeding coefficients or covariances for each pair of mates. For example, you can use the following statement to specify the mating of an individual named ‘David’ with an individual named ‘Jane’:

   matings david / jane;
