These functions generate sub-trees consisting of all
genotypes (and their conditional probabilities) that can result after
selfing the parental genotype.
Three (three-marker genotypes) or two (two-marker
genotypes) character string with the configuration of gamete one and two of
the parental genotype.
Value
A list with one element per possible genotype. Each
element is itself a list with two elements. Element
[[1]] holds the genotype configuration as "gam1-gam2" (e.g.,
"ABA-BAB"), element [[1]] the symbolic formula
representing the probability of observing this genotype given the
parental genotype.
