'Exotic mix' means that the writer's relatives come from lots of different backgrounds. For example, perhaps one grandparent is Irish, another is Malaysian, a third is Argentinian and the fourth is Russian. Each of these grandparents contributes their unique genetics and together they make up the writer's gene pool.

Not one person in the exotic mix of my family gene pool has ever shown any obvious signs of having what August has. What does "exotic" and "gene pool" mean here? Exotic = the non common result of a genetic mix. Gene pool = the genes 🧬 😊

Hi Cemre! 'Exotic' in this context means non-white or a mix of different ethnicities. 'Gene pool' is another way of saying 'genetics'. Hope this is helpful!
