  • a Expressed as percentage of difference between F1 (0.0028) and mauritiana (−0.0230).

  • b Expressed as percentage of difference between simulans (0.0337) and F1 (0.0028).

  • c 100 (Embedded Image ), see Equation 4.

  • d The average of additive effect estimates from the two backcrosses.

  • e QTL in chromosome × do not contribute to the difference between simulans and F1.
