Appearence and tactics of early 5th century Saxons.

[authun]

They (in the 'apartheid' article) describe a process whereby Anglo-Saxon males take priority in mating-rites with native British females as a method for replacing the native British Y-Chromosomes in the succeding generations.

That's not quite right. The model ran by setting U = D. That means there is an equal opportunity for AS men and RB men.

The reproductive selective advantage is S. Values for S that were greater than 1 were tested.

This factor can be influenced by several mechanisms, female mate choice, marriage system, infant mortality, etc. In this study, elevated status translating into reproductive advantage is investigated, ie. a female choice.

Examples where U does not equal D might be religious bans, cultural taboos or law.

A possible example where S might be less than 1 is where the first son of wealthy parents enters a celibate priesthood.
