TABLE 2.

Bateman–Mukai mutational parameters for second chromosome viability (V*)

Parameter Chavarrías et al. (2001) Present experiment
ΔMII × 10−2 0.140 ± 0.023 0.344 ± 0.034
ΔVII × 10−3 0.087 ± 0.029 0.197 ± 0.292
λII 0.023 ± 0.011 0.058 ± 0.072
E(s) 0.062 ± 0.023 0.057 ± 0.084

ΔMII and ΔVII are, respectively, the estimates of the rates of decline in mean and increase in variance, and λII and E(s) are, respectively, the Bateman–Mukai estimates of the rate (lower bound) and average effect (upper bound) of second chromosome mutations, obtained in Chavarrías et al. (2001) from generation 255 data and in the present experiment from generation 46 data.
