Genetic Basis of Tooth Development in the Stickleback
In my project, I will attempt to determine whether an isolated population of threespine stickleback fish from Scout Lake has undergone natural selection within a period of six years. I will do this by counting tooth number and determining if there has been a change in average tooth number across multiple generations. In addition, I will be investigating the different chromosomal loci and alleles that contribute to and determine total tooth number in several stickleback clutches. To do this, I will be genotyping their genomic DNA at these loci and performing in-situ hybridization to determine the patterns of genetic expression that regulate tooth number.
