The increasing ozone layer depletion due to exposure to high environmental pollutants may contribute to the high probability of cells being exposed to UV radiation, causing various cellular responses, such as genomic instability. This study aimed to determine the effect of UV on the frequency of crossing over in a cross between the wild-type and the black vestigial strain of Drosophila melanogaster, using four variations of duration UV exposure as follows: 0', 3', 6', and 9'. Recombinant progeny were calculated and analyzed using single-factor ANOVA. The results showed that: (1) The longer the duration of the UV exposure, the higher the percentage of recombinant progeny. (2) The body size of the D. melanogaster progeny exposed to UV light was more petite, and their movements were slower. (3) The single factor ANOVA showed that the length of UV had not affected the frequency of crossing over; but there was a phenomenon of crossing over, which has been showed that UV exposure made higher the percentage of recombinant progeny and affected to the body size of D. melanogaster. Therefore, further research is needed to examine the effect of UV radiation with longer periods of crossing over frequency and molecular analysis needs to be considered. © Published under licence by IOP Publishing Ltd.
