Table 2 Comparison of recombination frequency (cM) between the Aco-1 and Pgd-c loci for crosses involving S16L × SS-series of plants, and Bry × S16L

From: Meiotic recombination in Turnera (Turneraceae): extreme sexual difference in rates, but no evidence for recombination suppression associated with the distyly (S) locus

  1. Abbreviations: NS, not significant; Rec, recombination.
  2. Ghet values compare whether the observed frequencies differ statistically. For 2004, five crosses were compared with 4 degrees of freedom. For 2005, two crosses were compared with 1 degree of freedom. The P-values were obtained from one-tailed Fisher's exact test comparing the pooled vs the S16L × Bry crosses (or its reciprocal).
