Sex-specific life histories modulate the responses to a change in population size on the X and autosomes. We consider a scenario in which the autosomal population size dropped from $N_A=10,000$ to $N_A=1000$ at time $t=0,$ and show the response of the X:A diversity ratio afterward. We assume an autosomal generation time of 30 years, a sex-ratio of mutation rates of $\alpha =1,$ with the reproductive variances and generation times ratios specified in the legend.
