UJI LETAL RESESIF TERPAUT SEKS AKIBAT PEMBERIAN TIMBAL ASETAT DALAM MENGINDUKSI MUTASI LETAL PADA LALAT BUAH (DROSOPHILA MELANOGASTER)
ABSTRAK: The research was
carried out to study the effect of lead acetate induced lethal mutation on Drosophila melanogaster by using lethal sex
linked recessive test. The method was used experimental completely randomized
design ( RAL ) which repeated 20 times. Both of treatment and control were
crossed 30 times. Lead acetate 5034 ppm was given to the normal male D. melanogaster
used adult feeding method, while control was given by distilled water. The male
was crossed with the virgin female mutan basc and the second generation (F2) of
this culture was observed. The parameter observed were the sum of the lethal
culture (culture without normal D. melanogaster), non lethal culture (culture
with normal D. melanogaster), and sterile culture (culture with total
population less than 20). The data was analyzed by using t-test method. The
result showed that the mutation rate value of the treatment group was higher
tha the control group and significantly different (a = 5%)
