Final answer:

Sex-linked inheritance involves traits controlled by genes on the X or Y chromosome, showcasing distinct inheritance patterns between males and females.


Explanation:

Sex-linked inheritance refers to traits controlled by genes located on the X or Y chromosome. In humans, most sex-linked traits are located on the X chromosome. This results in distinct patterns of inheritance between males and females due to differences in their sex chromosomes.

One example of a sex-linked trait is red-green color blindness, which is an X-linked recessive condition. Males are more commonly affected by X-linked recessive traits due to having only one X chromosome, while females need two copies of the recessive allele to express the trait.

Understanding penetrance and expressivity is crucial in sex-linked inheritance as traits can vary in their manifestation based on genetic and environmental factors, highlighting the complexity of genetic inheritance.
