Genetic control of avian plumage traits
This project is a collaboration between Professor Terry Burke and Dr Vincent Cunliffe of the Centre for Developmental Genetics, Department of Biomedical Science, University of Sheffield.
Part 1: Towards the mechanisms underlying sexual selection
Genetic control of avian plumage traits: towards the mechanisms underlying sexual selection. Avian plumage traits provide one of the classic examples of sexual selection by female choice. The project aims to understand the molecular basis of plumage signals in the chicken, using a microarray approach, and then go on to identify the genes that have evolved in response to sexual selection.

Part 2: A candidate gene approach
Lavender is a pigmentation dilution mutation common among mammalian species. Several species of bird, such as chicken, quail, guinea fowl, muscovy duck, pigeon and blackbird, also have mutants showing a similar phenotype. I will initially begin with a study of 3 candidate genes, Myo5a, Rab27a and MLPH, known to be involved in this mutant phenotype in mammals, in the lavender chicken.
Once a mutation at one locus has been found to be associated with lavender I will extend my candidate gene approach to other species of bird to determine if mutations in the same gene can account for these diluted phenotypes also.
