Male mutant phenotypes

Mutation	Copulation*	Fertility	Sperm motility	Map position‡
40A-G13 (wild-type)	12/20	+	+
5G23	11/20	+	+
5L3	0/20	−/+†	+	between G13 and c
5M8	12/20	−†	−(thick sperm)	distal to G13
5N18	20/20	+	+
5N30	16/20	−	−(degenerate testes)	between G13 and c
5P1	6/20	+	+	near Bl

^*Number of males, from a total of 20 tested, that copulated with females within 30 min. 

^†Some 5L3 males eventually did court and produce offspring after several days. One 5M8 male produced offspring after several days. 

^‡Map positions of the auditory behavior phenotype are indicated for 5L3, 5M8, and 5N30. 5P1 was mapped on the basis of the sedentary phenotype (see text). In addition, the male sterility of 5M8 was mapped near c, and that of 5N30 was mapped between pr and G13. The G13 insertion site is at 42B on the polytene chromosomes.
