p_from_alpha: Obtain gamete frequencies at equilibrium given rates of double reduction.
Description
Given the rate of double reduction and the major allele frequency, this
function will calculate the gametic frequencies.
Usage
p_from_alpha(alpha, p, ploidy)
Value
A numeric vector of length ploidy / 2 + 1, where element
i is the probability that a gamete carries i-1 copies of
the major allele.
Arguments
alpha
A numeric vector containing the double reduction parameter(s).
This should be a
vector of length floor(ploidy/4) where alpha[i]
is the probability of exactly i pairs of IBDR alleles
being in the gamete. Note that sum(alpha) should be less than
1, as 1 - sum(alpha) is the probability of no double reduction.
