Calculates the upper bounds of the double reduction parameters according to the complete equation segregation model. See Huang et. al. (2019) for details.
drbounds(ploidy)The ploidy of the species. Should be even and at least 4.
A vector of length floor(ploidy/4). Element i is
the upper bound on the probability of i pairs of
identical-by-double-reduction alleles being in an individual.
