a The crosses used to create hybrids with D. sechellia chrX (sechXF1) and b hybrids with D. simulans chrX (simXF1). c The crosses used to create backcross progeny. Autosome and sex chromosome genotypes are represented by colored squares (A autosome, X&Y sex chromosomes, orange D. sechellia chromosome, blue D. simulans chromosome). d CF for each male type when paired with D. simulans females (N = 76, N = 30, N = 70, N = 57, N = 952, and N = 77, for blue bars from left to right) or with D. sechellia females (N = 96, N = 30, N = 59, N = 55, N = 952, and N = 79, orange bars from left to right). e CF for each male type when paired with sham-perfumed D. simulans (N = 19, N = 23, N = 16, and N = 20, for blue bars from left to right) or 7,11-HD-perfumed D. simulans females (N = 20, N = 25, N = 25, and N = 20, orange bars from left to right). Whiskers represent 95% confidence intervals from a binomial test.
