T is the K-carrier frequency attained as a threshold at the last genotyping, after which selection ceases. For each T-value, the figures drawn up in the next columns are the K-carrier frequencies (average values for different patterns of age structure, as exemplified in Additional file 5) of the last genotyping (the former value) and the year at which the K-carrier frequency becomes constant (final frequency, i.e., the latter value).
(1) KK frequency in progeny at the year that the K-carrier frequency becomes constant and the frequency of K allele in parenthesis.
