In dartR: Importing and Analysing 'SNP' and 'Silicodart' Data Generated by Genome-Wide Restriction Fragment Analysis

Simulates a specified number of offspring based on alleles provided by potential father(s) and mother(s)

Description

This takes a population (or a single individual) of fathers (provided as a genlight object) and mother(s) and simulates offspring based on 'random' mating. It can be used to simulate population dynamics and check the effect of those dynamics and allele frequencies, number of alleles. Another application is to simulate relatedness of siblings and compare it to actual relatedness found in the population to determine kinship.

Usage

gl.sim.offspring(fathers, mothers, noffpermother, sexratio = 0.5)

Arguments

fathers	Genlight object of potential fathers [required].
mothers	Genlight object of potential mothers simulated [required].
noffpermother	Number of offspring per mother [required].
sexratio	The sex ratio of simulated offspring (females / females +males, 1 equals 100 percent females) [default 0.5.].

Value

A genlight object with n individuals.

#Simulate 10 potential fathers
gl.fathers <- glSim(10, 20, ploidy=2)
#Simulate 10 potential mothers
gl.mothers <- glSim(10, 20, ploidy=2)
gl.sim.offspring(gl.fathers, gl.mothers, 2, sexratio=0.5)
