Various population genetic processes can lead to the loss of gene function from a chromosome that is prevented from crossing over Charlesworth ; Rice ; Orr and Kim In May a paper published in bioRxiv presented an electron microscopy image stack of the whole adult female brain at synaptic resolution.

The signal pathway leading to this change in behavior has been determined. Flies fly via straight sequences of movement interspersed by rapid turns called saccades. Bibcode : SciNa. When a nonrecombining chromosome carries one or more strongly deleterious mutations, it will be rapidly eliminated from the population; only chromosomes free of such mutations contribute to the future ancestry of the population, such that the effective population size depends largely on the size of the mutation-free class Charlesworth, Morgan, and Charlesworth
