Crosses in which a backcross or intercross were conducted with the F1 offspring of a P1 parental cross. For each family, number of offspring as well as the observed yellow:green color ratio, the expected color ratio and the P-value yielded by a two-sided exact binomial test for both F1 and F2 provided. Two pairs of F1 family 14 offspring were successfully mated resulting in two F2 generations within family 14.
