Inbreeding avoidance hypothesis
WebWhile the hypothesis was not supported, a lack of resolution from the markers cannot be ruled out given the very poor genetic diversity in albatrosses. Some perspectives about inbreeding-related aspects (e.g. inbreeding avoidance, purging) based on recent literature are also proposed.
