Posterior probabilities of the genotypes for a missing parent conditional on the available parent and offspring

Off-spring	Parent 1	Parent 2
		0	1	2
0	0	$\frac{2{\mu }_1}{2{\mu }_1+{\mu }_2}$	$\frac{{\mu }_2}{2{\mu }_1+{\mu }_2}$	0
0	1	$\frac{{\mu }_2}{{\mu }_2+2{\mu }_5}$	$\frac{2{\mu }_5}{{\mu }_2+2{\mu }_5}$	0
1	0	0	$\frac{{\mu }_3}{{\mu }_3+{\mu }_4}$	$\frac{{\mu }_4}{{\mu }_3+{\mu }_4}$
1	1	$\frac{{\mu }_3}{{\mu }_3+2{\mu }_6+{\mu }_8}$	$\frac{2{\mu }_6}{{\mu }_3+2{\mu }_6+{\mu }_8}$	$\frac{{\mu }_8}{{\mu }_3+2{\mu }_6+{\mu }_8}$
1	2	$\frac{{\mu }_4}{{\mu }_4+{\mu }_8}$	$\frac{{\mu }_8}{{\mu }_4+{\mu }_8}$	0
2	1	0	$\frac{2{\mu }_7}{2{\mu }_7+{\mu }_9}$	$\frac{{\mu }_9}{2{\mu }_7+{\mu }_9}$
2	2	0	$\frac{{\mu }_9}{{\mu }_9+2{\mu }_{10}}$	$\frac{2{\mu }_{10}}{{\mu }_9+2{\mu }_{10}}$

We assume, with no loss of generality, that parent 2 is the parent missing genotype data.
