Mimicking breeding program in WF model

[Jingyi Gao]

Hi,

I am trying to mimic an animal breeding program on SLiM. Ideally the population will consist of 1000 animals (500 males and 500 females),  in each generation, the best 25 males are selected on the basis of their genetic value for a single polygenic trait (similar to a ornamental trait) and mated to the females to produce 1000 replacement animals. I tried to simulate this mate selection process using mateChoice( ) function but mateChoice( ) function is specific for every focal individuals so I will not be able to arrange each female to mate with the 25 selected males equally (as each time the focal individual will not remember previous mating).  

I want to ask is it feasible to mimic this animal breeding program under WF model on SLiM? if so what function/callback is appropriate?

Best wishes,

Jingyi

Hi Jingyi.  For this kind of specific control over patterns of mating, a nonWF model is recommended.  You can still have the model mimic a WF model in most respects (non-overlapping generations, fitness governing mating not survival, etc.) as you wish; see section 16.15 of the manual, for example.  The nonWF model type will allow you to follow the exact pattern of mating you want very easily.  If you're unfamiliar with nonWF models, you might find it easiest to start by doing the SLiM workshop, which is available online for free.  Please post again if you end up stuck on any specific questions.  Happy modeling!

Cheers,
