dc.description.abstractTwo different natural populations of Drosophila melanogaster were surveyed to determine the types of inversions present by examining the salivary gland chromosomes of third instar larvae. Seven different inversions were detected in populations, Tejuosho market and Bariga market (Lagos, south-western Nigeria) populations. All inversions detected were single, paracentric and autosomal. The inversions observed were distributed in the arms of the chromosomes as follows: two in the left arm of chromosome 2 (2L), one in the right arm of chromosome 2 (2R), two in the left arm of chromosome 3 (3L) and two in the right arm of chromosome 3 (3R). Some inversions occurred together with other inversions in the same larva and this occurrence was probably just due to chance but also indicates that such conditions were not lethal. Some of the inversions detected in this study had been recorded by earlier researchers in some parts of south-eastern Nigeria and south-western Nigeria. The occurrence of similar inversions in these regions may be evidence that the inversions are not recent. This similarity in inversions also suggests that there is or had been migration from one place to the other or the inversions originated somewhere else and had been transported to other places.en_US
