Solution
The inheritance pattern where more males than females are affected is typically indicative of a sex-linked recessive trait. This is because males have only one X chromosome, so if they inherit the X chromosome with the recessive trait, they will express that trait. Females, on the other hand, have two X chromosomes, so they would need to inherit the recessive trait on both X chromosomes to express it. Therefore, the answer is sex-linked recessive.
