get_q_array {updog}

Return the probabilities of an offspring's genotype given its parental genotypes for all possible combinations of parental and offspring genotypes. This is for species with polysomal inheritance and bivalent, non-preferential pairing.

Description

Return the probabilities of an offspring's genotype given its parental genotypes for all possible combinations of parental and offspring genotypes. This is for species with polysomal inheritance and bivalent, non-preferential pairing.

Usage

get_q_array(ploidy)

Arguments

ploidy

A positive integer. The ploidy of the species.

Value

An three-way array of proportions. The (i, j, k)th element is the probability of an offspring having k - 1 reference alleles given that parent 1 has i - 1 reference alleles and parent 2 has j - 1 reference alleles. Each dimension of the array is ploidy + 1. In the dimension names, "A" stands for the reference allele and "a" stands for the alternative allele.
