Sex Linked Gene

Real World Example

Imagine you're trying to decide which movie to watch, but your choice is limited because it's determined by the preferences of the person who owns the streaming account. This situation is similar to how a sex-linked gene operates because, just like the movie selection is influenced by the account holder, the expression of a sex-linked gene is influenced by which sex chromosome it resides on. In this analogy, the streaming account holder represents the sex chromosome, determining the available movie (or in the case of genetics, whether the gene will be expressed), illustrating how traits linked to sex chromosomes are inherited differently depending on whether they are on an X or a Y chromosome.
