A repetitive perspective on sex-specific and tissue-specific genome differences of birds

any animals have either sex-specific genome differences such as sex chromosomes or tissue specific genome differences such as germline-restricted chromosomes (GRCs), both of which are expected to evolve differently from the remaining "shared" genome. Songbirds are a particularly peculiar case as their autosomes are highly syntenic and collinear, yet their female-specific W sex chromosomes and their mainly female-inherited GRCs are extremely rapidly evolving. Here I will review our last 8 years of research on Ws and GRCs from a repetitive perspective, suggesting that rapid evolution of these chromosomes may explain sex differences in repeat accumulation and tissue differences in expression variation.---( Appel vidéo )----
