Sperm phenotyping - bright field vs. epifluorescence. Scatter plot of the number of fluorescent sperm assessed in a live GFP(-) recipient, under bright field and epifluorescence illumination. Small size dots represent individual replicates, intermediate size dots represent two overlapping replicates, and the big size dot represents 12 overlapping replicates. The dashed line displays the expected line of equality. See text for statistics.
