Viability and Sexual Selection in Simultaneous Hermaphrodites

Here I studied, the dynamics of a population of sexuals and asexuals simultaneous hermaphrodites as a function of their fitness ratio. This work is an extension of Joshi and Moody (1995). There are two locus in the model, one for mode of reproduction, the other for viability selection / sexual selection. Stability analysis was performed to find the conditions under which the alleles goes to fixation. Statisitcal Modelling was done using parameter values to gain an understanding of parameter space.

Allele Simulations

In this project, I recreated a software "Allele A1" which models evolution at a single locus. The software was originally created by John C Herron (University of Washington). The code and the GUI has been created using python.

Infinite Alleles Model

The infinite Alleles Model was given by Kimura and Crow in 1964. In this project, I run computer simulations to plot the differences between the theoretically predicted value of the mean loss time of mutations and the actual loss time using simulations. As you can see the difference is less than 1 generation.

Infinite Alleles Model using Non-Random Mating

Evolutionary models usually assume random mating for the sake of simplicity. But sometimes they are an oversimplification. In this project, I have tried to implement a recommender system like model for mating. I used collaborative filtering and k-Nearest Neighbor algorithm to see how it would effect mean loss times and how different it would be from theoretically predicted values.

Modifier Traits for Sexual Conflict

This is a quantitative genetics model which uses Breeder's equation and describes a system of a sexually conflicted trait that is affected by modifier alleles. The correlation between the traits along with optimum values are all used as parameters to study the system.
