Though I find cheating/conflict theoretically fun to think about, I strongly resonate with this. To me it feels like a much harder problem to study is the reduction in (eff.) pop. size during an ETI, causing a dramatic increase in the strength of stochasticity in determining evolutionary outcomes.
Abstract. Many species of Colias butterflies show a female-limited colour polymorphism where the dominant Alba allele leads to white wings, faster developm
