¹The analysis for age at puberty contained 191 observations, mean = 195 ± 27 days (mean ± std dev), range = 135 – 266.
²233 observations for ovulation rate, mean = 13.7 ± 2.4 corpora lutea, range = 9 – 21.
³1144 observations for nipple number, mean = 14.6 ± 1.06 nipples, range = 11 – 19. Genotype probabilities were calculated for all F8 and F10 animals in the population using GenoProb [50].
⁴Values indicate p-value and estimated genotype effects in parentheses. The allele frequencies for F8 and F10 animals are given in Table 2.
