ETHYL METHANESULPHONATE-INDUCED MALE RECOMBINATION AND CHROMOSOMAL ABERRATIONS IN DROSOPHILA MELANOGASTER

Published on

Ethyl methanesulphonate (EMS)-induced stable chromosomal aberrations did not show a
direct association with male recombination in Drosophila although one out of four
chromosomal aberrations observed in the TCI larvae overlapped the dp-b region. Highest
frequency of male recombination was observed in the dp-b region. No aberrations was
observed in TCI larvae decendents and FI larvae larvae of the cross involving female
from a homozygous male recombinant line and a male from the complementary
stock, or its reciprocal. Thus, involvement of chromosomal aberrations in male
recombination in D. melanogaster still remains an open question and warrants further
investigation.
