Morphology
X-linked + dominant + inheritance
Each component contributes directly to the overall meaning: 'X-linked' specifies location on the X chromosome, 'dominant' indicates the allele is expressed when present, and 'inheritance' denotes transmission across generations. Although technical, the phrase is compositionally predictable from its parts, so a learner who understands the constituent terms can infer the MWE's meaning.
Etymology
X-linked dominant inheritance paints a simple picture: a change on the X chromosome is X-linked, the change is dominant — 'one copy is enough' — and it is inherited, meaning 'passed from parent to child'. That's why the term means a trait caused by a dominant gene on the X chromosome that shows up in children who get it.
