segreg_poly {mappoly}

Polysomic segregation frequency

Description

Computes the polysomic segregation frequency given a ploidy level and the dosage of the locus in both parents. It does not consider double reduction.

Usage

segreg_poly(ploidy, dP, dQ)

Arguments

ploidy

the ploidy level

dP

the dosage in parent P

dQ

the dosage in parent Q

Value

a vector containing the expected segregation frequency for all possible genotypic classes.
