- Population-Genetic Models for Genomically Imprinted Loci
Genomic imprinting describes the unequal expression of paternally and maternally inherited genes in mammals. We are interested in the population-level consequences of this form of non-Mendelian expression.
- Evolutionary Origin of Genomic Imprinting
There have been several hypotheses proposed for the evolution of the unequal expression of paternally and maternally inherited genes in mammals. We are interested in examining these hypotheses rigorously, using novel mathematical models.
- Phylogeography of Molluscs
Molluscs often provide ideal models to investigate questions in phylogeography, including questions about the importance of dispersal. New Zealand (and the South Pacific in general) has a diverse terrestrial and marine molluscan fauna that has already provided such model systems. We are interested in using novel DNA data sets in phylogeographic investigations.
- Testing the Power to Detect Neutral Polymorphisms
Many of the statistical tests of the neutral hypothesis of evolution do not detect non-neutral systems easily. This project involves examining the power of a number of these tests for polymorphisms constructed by mutation and selection.
- Frequency-Dependent Selection and Genetic Variation
In theory, frequency-dependent selection can maintain large numbers of alleles in a population. We are interested in quantifying this ability and seeing if, in fact, this form of selection might be responsible for the standing variation observed in natural populations.
- Evolutionary Genetics of Parental Effects
It is becoming increasingly clear that parents pass on more than just their genes to the offspring. For example, experiments with a species of weedy cress have shown that non-genetic factors inherited from grandparents can even alter the genetic constitution of individual plants. This project will construct mathematical models that show how various parental effects can have long-term evolutionary implications.
