Table A.6.

A scheme for rearranging two shared alleles to get one shared allele and larger F.

	b ≥ c		b < c
Subpopulation	Allele 1	Allele 2	Allele 1	Allele 2
1	a + c	b − c	a + b	0
2	0	d + c	c − b	d + b
Mean	$\frac{a+c}{2}$	$\frac{b+d}{2}$	$\frac{a+c}{2}$	$\frac{b+d}{2}$
Product	0	(b − c)(d + c)	(a + b)(c − b)	0
