Table 1. Summary of notation.

Term	Definition
K	Ploidy of the species.
$x_{ij}$	jth read for ith individual.
	Equal to 1 if a read is an A and 0 if a read is an a.
$y_i$	$={\displaystyle {\sum }_j{x}_{ij}}$. The number of A reads in individual i.
$n_i$	Number of reads in individual i.
$p_i$	Allele-dosage for individual i, $p_i\in \left\{0/K,1/K,\dots ,K/K\right\}$.
${\theta }_i$	Probability sample i is a nonoutlier.
${\stackrel{\sim }{y}}_{\ell }$	Number of A reads in the $\ell$th parent.
${\stackrel{\sim }{n}}_{\ell }$	Number of reads in the $\ell$th parent.
${\stackrel{\sim }{p}}_{\ell }$	Allele-dosage for the $\ell$th parent.
${\stackrel{\sim }{\theta }}_{\ell }$	Probability the sample from parent $\ell$ is a nonoutlier.
ϵ	Sequencing error rate.
h	Allelic bias parameter. $Pr\left(\text{a observed after selected}\right)/Pr\left(\text{A observed after selected}\right).$
τ	Overdispersion parameter for the read counts.
π	Proportion of samples that are nonoutliers.
