Indeed, copulation behavior in wild-type is vigorous and highly resistant to environmental stress such as a strong smell of ether.
We also find that the change of arena size does not affect copulation success in wild-type.
Successful copulation is a consequence of sexual interactions between specific male stimuli and appropriate female responses.
2E) with no significant difference (P = 0.71, Fisher’s exact test) (Fig. Similar data was obtained using another duplication line. Copulation success was increased from 6.3% for heterozygous to 87.5% for homozygous 10×UAS-IVS-m CD8:: GFP (on III) flies (Fig. Similar results were observed as 0.0% to 75.0% in 10×UAS-IVS-m CD8:: GFP (on II), 12.5% to 75.0% in 20×UAS-IVS-m CD8:: GFP (on III), 12.5% to 56.3% in 10×UAS-IVS-m CD8:: GFP;10×UAS-IVS-m CD8:: GFP (on II and III), 6.3% to 56.3% in 10×UAS-IVS-m CD8:: GFP;20×UAS-IVS-m CD8:: GFP (on II and III), 0.0% to 43.8% in UAS-hsp70#4.4 (on III), 0.0% to 15.4% in UAS-hsp27; UAS-hsp26 (on II and III), and 6.3% to 18.8% in UAS-Httex1-Q47-e GFP (on III) (Fig. The increase of copulation success for each UAS line was observed from flies with heterozygous mw allele to flies with homozygous alleles carried in the same transposon.
For all the experiments, copulation success is indicated as red in the pie chart.
Sexual activities of flies was observed within 60 minutes in the circular arenas.
(B) Courtship indices within three minutes in tested flies.
*P males but not heterozygous males started courtship immediately.
