The table shows the mating of two sires to three cows and the resulting mean and standard deviation of the potential offspring. In addition, the table shows the probability (p) and minimum number of animals (N) to test, to generate at least one offspring over 0_, 1, 2_, 3_, or 4 genetic standard deviations (σ_a) for protein yield.
