The genetic lottery hits different depending on your chromosomes! Since recessive sex-linked disorders are carried on the X chromosome, girls with their XX setup get a backup copy if mom or dad passes along a faulty gene. Meanwhile, boys with XY chromosomes are basically playing genetic Russian roulette - if their only X chromosome (thanks, mom) has that recessive trait, they're stuck with the full disorder. No wonder the boy looks like he's having an existential crisis while the girl maintains her composure. Procrastinating on studying for genetics by making genetics memes? That's some high-quality academic self-sabotage right there.
