From: Predicting the impact of selection for scrapie resistance on PRNP genotype frequencies in goats

  K-carrier frequency

Saanen
 Overall average   0.50   0.98 4.3 9.9 11.7 0.51 (0.75)
 Average 1   0.51   0.99 4.3 9.6 11.4 0.53
 Average 2   0.51   0.98 4.0 9.3 11.5 0.51
 Average 3   0.52   0.99 4.0 9.0 11.3 0.53
Chamois Coloured
 Overall average 0.55   0.99   1.7 7.2 9.2 0.52 (0.76)
 Average 1 0.55   1   1.7 6.9 9.0 0.54
 Average 2 0.54   0.99   1.5 6.8 9.2 0.52
 Average 3 0.54   1   1.5 6.5 9.0 0.55
  1. The averages are computed on the different patterns of age structure of Additional file 1.
  2. Average 1 is the average excluding a female replacement rate of 0.15. Average 2 is the average excluding a male replacement rate of 0.50. Average 3 is the average excluding both a female replacement rate of 0.15 and a male replacement rate of 0.50.
  3. (1) Year the replacements are all K-carriers. (2) Year the replacement bucks are all KK. (3) Year the K-carrier frequency in progeny is > 0.99. (4) KK frequency in progeny at year (4) and frequency of K allele in parenthesis.
