Sex chromosomes have evolved many times across the tree of life. Loss of genes and sequence degeneration has long been the defining feature of Y chromosomes. But in addition to degeneration, Y chromosomes undergo a diverse range of modifications such as gene duplication, chromatin modifications, and mutations that alter expression of genes. My work is dedicated to understanding how gene regulation and chromatin modifications evolve on the sex chromosomes. I am studying the recently evolved sex chromosomes of threespine stickleback fish to identify changes in gene expression and histone modifications that are altered early in the formation of sex chromosomes.
