| The objective of this study was to evaluate the effects of boron (B) using as a biological model Drosophila malanogaster. Analizing specifically the responses over descendency to doses of 6,0 and 12 mg/L, comparing a control group which culture medium was prepared with water with boron concentrations of 0,6 mg/L, according to World Health Organization. The results show a significative alteration in the number of descendency from F1 to F3 and then a tendency to normalization in F4 and F5. Also a significant change in proportions between the males and females, with an acute effect on F1 and then a possible chronic effect from F2 to F5, increasing the proportion of females over males. This differences between genders are significant only until F4, on F5 these... |
