  • a Z femaleness is the DI value defined by -ln(nUM × nMZ/nUZ × nMM), where nij is the number of copulating pairs between type i females and type j males; U, Z, and M designate the tested lines (U, unknown), pure Z lines, and pure M lines, respectively. The four nij numbers are given in the parentheses.

  • b Z femaleness as recorded in Hollocher et al. (1997a); see materials and methods.

  • c Numbers in parentheses show the Z femaleness range among tested lines.

  • d Zimbabwe, Harare (ZH); Zambia, Luangua (LA); Botswana, Okavanga (OK).
