Abstract

Determination of the nature of chromosomal alterations may be based on examination of changes occurring in nature or of those which arise spontaneously or are induced experimentally. Although the changes existing in natural populations of Drosophila are more widespread and diversified than was formerly suspected (see review by Dobzhansky, 1941), they obviously represent a residual group which has survived the control of natural selection. Thus inversions form by far the largest store of types detectable in these natural populations, although translocations as well as inversions are known to arise both as a result of X-ray treatment and spontaneously. Chromosomal alterations that have occurred in the phylogeny of Drosophila, as inferred through comparisons of the gene arrangements of related species, consist also largely of inversions, combined with rearrangements involving entire chromosome limbs and only very few short interstitial translocations.
