... undergo purging as populations which experience a slow rate of increase in inbreeding over time are more likely to show the effects of purging [24] and the rate of increase of inbreeding in the Irish ... affect the inbreeding effect. Favourable coefficients for the inter- action suggest the occurrence of purging of inbreeding depression for that trait...
