Figure C.2: With a transmission error rate of $\epsilon = 0.1$ the uniparental transmission model has similar results to the version in the main text. There is a range where the reproductive cost of teaching is about half the reproductive benefit of the trait where the trait persists at a low frequency (A), females are taught at a high rate (B), and males are taught at a much lower rate (C). However, the trait frequency is low over a greater range than in the model in the main text.
