Documentation for SLiM function initializeSex, which is a method of the SLiM class Initialize. Note that the R function is a stub, it does not do anything in R (except bring up this documentation). It will only do anything useful when used inside a slim_block function further nested in a slim_script function call, where it will be translated into valid SLiM code as part of a full SLiM script.

initializeSex(chromosomeType)

Arguments

chromosomeType

An object of type string. Must be of length 1 (a singleton). See details for description.

Value

An object of type void.

Details

Documentation for this function can be found in the official SLiM manual: page 654.

Enable and configure sex in the simulation. The argument chromosomeType gives the type of chromosome to be simulated; this should be "A", "X", or "Y". Calling this function has the side effect of enabling sex in the simulation; individuals will be male and female (rather than hermaphroditic) regardless of the chromosomeType chosen for simulation. There is no way to disable sex once it has been enabled; if you don't want to have sex, don't call this function. The xDominanceCoeff parameter has been deprecated and removed. In SLiM 3.7 and later, use the haploidDominanceCoeff property of MutationType instead. If the chromosomeType is "X", the optional xDominanceCoeff parameter can supply the dominance coefficient used when a mutation is present in an XY male, and is thus "heterozygous" (but in a different sense than the heterozygosity of an XX female with one copy of the mutation).
