Invasion Experiment 2: Proportion of GFP-positive worms (Y-axis) over time (X-axis) after the addition of a single GFP marked virgin hermaphrodite (circles), male (triangles) or mated hermaphrodite (squares) to a population of 500 (A, B) or 100 (C, D) N2 worms on day 0. The added worms were of strain QA354 (essentially the genetic background of CB4856; A, C) or QA353 (essentially the genetic background of N2; B, D). The error bars designate standard errors. Each point is the average of 6 independent measurements. For the statistical analysis see Table 2.
