simulHS: Function to simulate half sib progeny genotypes

In simulMGF: Simulate SNP Matrix, Phenotype and Genotypic Effects

Function to simulate half sib progeny genotypes

Description

Simulate half sib progeny from one genotyped parent assuming a random genotype for the other parental. We assume that these are diploid organisms.

Usage

simulHS(x, Nprogeny)

Arguments

x	genotype matrix of a set of moms
Nprogeny	number of progeny's genotypes to simulate for each mom

Details

The function assume: a diploid organism; mendelian segregation of alleles; and independent segregation.

Value

a matrix of dimensions (nrow(x)*Nprogeny) x ncol(x)
