Velocity

Sperm velocity and sperm numbers in the SR. Variables: Treat - sxm indicates single mating between D. simulans female and D. mauritiana male, NR indicates "no remate" treatment, other treatments are rematings defined by the species identity of first and second male to mate with a D. simulans female, where "s" indicates D. simulans and "m" indicates D. mauritiana, such that "ss" indicates that both males were D. simulans, "ms" indicates that the first male was D. mauritiana and the second male was D. simulans, etc. Region – region of the female reproductive tract, bursa or SR. Male – species and color tag of male whose sperm velocity is recorded. Order - first or second male to mate. Remate - for remating treatments, day after first mating (day 0) on which female remated. Velmps – instantaneous linear velocity in microns per second, averaged for each sperm and for all sperm recorded in a movie. N – number of sperm tracked per movie. SR.G – number of GFP sperm in the SR. SR.R – number of RFP sperm in the SR.
