Shelly and Jason are siblings but Shelly looks like their father while Jason looks like their mother. Which of the following statements best explains the difference in Shelly's and Jason's features?

The difference in Shelly's and Jason's features can be attributed to genetic inheritance, where each sibling inherits a unique combination of genes from both parents.
