beta_bounds {segtest} | R Documentation |
Bounds on the distortion at simplex loci caused by double reduction.
Description
The frequency of (nullplex, simplex, duplex) gametes is (.5 + beta, .5 - 2 * beta, beta). This function returns the upper bound on beta under two models.
Usage
beta_bounds(ploidy, model = c("ces", "prcs"))
Arguments
ploidy |
The ploidy |
model |
Either complete equational segregation ( |
Details
Returns the upper bound on the probability of a gamete with a genotype of 2 when the parent has a genotype of 1. This is based on two models. The upper bound from complete equational separation is higher than the upper bound from the pure random chromatid segregation. See Huang et al (2019) for a description of these models.
Value
The upper bound on beta.
