Probability of an individual of Gracilaria chilensis to be fecund (ρ) across different frond size categories (ln(v)). Labels are (M) males, (F) females, and (D) diploids, (obs.) observed and (est.) estimated. Individual sizes are given by the frond volume (v) in cm3. Gompertz curves fitted by the Newton-Rahpson method and confirmed by Levenberg-Marquardt algorithm. The probabilities of M, F and D curves to be equal, as estimated by χ2 tests, were always below 0.0002
