In this chapter, Ari engages in a thoughtful discussion with her mother (maman) about a biological problem involving fish genetics, exploring factors like sex ratios, predation, and mate preference. The conversation reveals the complexity of ecological and genetic interactions and introduces the idea of simplifying problems to focus on key variables. Meanwhile, Ari senses an underlying tension and sadness in her family, highlighted by changes in behavior and emotional distance, which contrasts with moments of affection and care.
