Sperm counts for flies with two (large filled circles, solid line) or three (large open triangles, dashed line) spermathecae. The data are jittered and dodged to better display overlapping values. a Sperm count per spermathecae versus days post copulation. The small circles show the raw data (2–3 values per female per day), whereas the large symbols show the predicted values for each female. The lines represent the least square regression lines for the predicted (conditional on the zero model) values. b Total sperm count versus days post copulation. The lines represent the predicted values from the zero-inflated generalized linear model. The data are jittered and dodged to better display overlapping values
