Ratnieks Assuming that on average autosomes and X chromosomes have a similar size, this leads to the testable prediction that species with very few chromosomes e. Ours, XY, is not even predominant. Mesquite: a modular system for evolutionary analysis.
Batches of worker bees are short lived and are constantly being replaced by the next batch, so this kin selection is possibly a strategy to ensure the proper working of the hive. All of the discussion of sex determination is interesting. Unfortunately, the adaptive advantages of chromosomal fusions are unclear.
