Even if the skew is driven by a minority of men it will still mean that women in their early twenties will experience a favorable mating market with many suitors, while women in their thirties and older will experience a mating market slightly skewed against them. At the very least, their ...
(n = 281, age ≥ 55). We found that the mean DS in LCLs was significantly higher in older than in younger females (DSyounger = 0.2, DSolder = 0.24,Ttest,P = 0.03; Fig.4). Accordingly, we found that the frequency of skewed XCI in LCLs was significantly ...

However, these attributes also mean that special care must be taken in population genetic inference. For example, highly skewed offspring distributions, frequent and severe population bottleneck events associated with infection and compartmentalization, and strong purifying selection all affect the ...
