Final answer:
X-linked inheritance is the inheritance pattern shown for a trait occurring in one sex but not in the opposite sex. This pattern is due to genes located on the sex chromosomes, specifically the X chromosome. Males, who have only one X chromosome, are more likely to be affected by X-linked traits.
Step-by-step explanation:
The inheritance pattern that is shown for a trait occurring in one sex but not in the opposite sex is X-linked inheritance. X-linked inheritance refers to the inheritance of traits that are located on genes on the X chromosome. Since males have only one X chromosome and females have two, there will be differences between the sexes in how these sex-linked traits are expressed.
A classic example of an X-linked trait is color blindness, which is more common in males. This is because the gene for color vision is located on the X chromosome and males only have one X chromosome, while females have two. Therefore, if a male inherits the recessive allele for color blindness, he will be affected, while females need to inherit the recessive allele from both parents to be affected.
