Neco 2019 Biology Question 34
Practice objective / multiple choice question 34 from the 2019 Neco Biology examination.
In a reptile species, sex is temperature‑dependent: incubation below \(20\ ^\circ\text{C}\) yields males, above \(30\ ^\circ\text{C}\) yields females, and between \(20\ ^\circ\text{C}\) and \(30\ ^\circ\text{C}\) produces both sexes in equal proportion. A clutch of 200 eggs is incubated with temperature increasing linearly from \(18\ ^\circ\text{C}\) on day \(1\) to \(32\ ^\circ\text{C}\) on day \(10\). Assuming the proportion of females corresponds to the fraction of the incubation period spent above \(30\ ^\circ\text{C}\), how many females are expected in the clutch?
