From Table 1, it appeared that females achieved slightly higher BECs than males and drank more. Although both measures increased over generations, the small sex differential remained stable (see Supplement 1). By S11, the estimate of inbreeding (see Supplement 1) was 12.8% through S11. These values are also given in Table 1. The rate of inbreeding during S6–S11 (approximately 1.4% per generation) is what would be expected for at least the next several generations.
