There has long been an assumption that normal disjunction of the sex chromosomes of all mammals is assured by synapsis of a region of homology between the X and Y and that an 'obligatory' crossover with chiasmata formation follows. Evidence is presented here that much (if not all) observed synapsis

The long arms of the X and Y chromosomes of the mosquito Anopheles atroparvus (2n equals 6) are equal in length, synchronous in their late DNA replication and have homologous G AND Q bands. This indicates that differentiation of the two sex chromosomes was the consequence of a single deletion of an
