Abstract

Chromosome elimination is a widespread developmental phenomenon in insects. The main types of chromosome elimination take place at early embryonic somatic cleavages and at the first male meiotic division. The cellular mechanisms responsible for both elimination types are different but show common aspects in Diptera, notably unusual anaphase behavior of the chromosomes to be eliminated. Chromosome elimination can be parent-of-origin specific, highlighting this phenomenon as an example of genomic imprinting.
