Solution
The inheritance pattern described, where males are affected more frequently than females, suggests that the condition is likely associated with the X chromosome. This pattern of inheritance is characteristic of sex-linked traits, typically X-linked recessive traits.
Explanation:
-
Sex-Linked Traits: A trait linked to genes located on the sex chromosomes. In many cases, for X-linked recessive disorders, males (who have one X and one Y chromosome) are more affected because they have only one copy of the X chromosome. If that chromosome carries the recessive allele, they will express the trait. Females (who have two X chromosomes) would require both of their X chromosomes to carry the recessive allele to express the trait, making the conditions less common in females.
-
Autosomal Traits: These traits are associated with genes located on the autosomes (non-sex chromosomes) and are typically not biased toward one sex.
Therefore, the correct answer from the provided choices is sex-linked traits.
