drbounds {segtest} | R Documentation |
Upper bounds on double reduction rates.
Description
Provides the upper bounds on the double reduction rates based on the formulas in Huang et al. (2019). There are two upper bounds provided. The upper bound from complete equational separation is higher than the upper bound from the pure random chromatid segregation.
Usage
drbounds(ploidy, model = c("ces", "prcs"))
Arguments
ploidy |
The ploidy |
model |
Either complete equational segregation ( |
Value
A vector of length floor(ploidy / 4)
containing the upper bounds
on the rates of double reduction. The i
the element is the
upper bound on the probability that there are i
pairs of
identical by double reduction alleles in a gamete.
