  1. Dashed line (−) indicates that the recombination rate in the male parent was zero and therefore undefined.
  2. *Significant G-tests at P < 0.001 following corrections for multiple tests.
  3. 1 Arrows indicate significantly greater (↑) or less (↓) YCT allele frequencies than expected within each parent–specific map (F1 Female 1, F2 Female 2, M1 Male 1, and M2 Male 2). The number in parentheses indicates the number of significant 25 cM intervals within a parent map.
  4. 2 Map distance is the product of the two groups in parentheses.
  5. 3 The genome wide map distance was calculated using the average map distance across RYHyb25 + RYHyb29 and RYHyb25_29 within each sex (i.e. ((RYHyb 25 + RYHyb 29) + RYHyb 25 _ 29)/2).
