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.

get_q_array(ploidy)
ploidy |
A positive integer. The ploidy of the species. |
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.

qarray <- get_q_array(6) apply(qarray, c(1, 2), sum) ## should all be 1's.
