Morphology
X + chromosome
The compound simply names a type of chromosome: 'X' (the letter/name) combined with 'chromosome' (a DNA structure) yields the straightforward meaning 'the chromosome called X.' Although specific inheritance details (single in males, double in females) require additional biological knowledge, the basic referent is compositionally transparent and readily inferred by learners who know both constituents.
Etymology
X chromosome gets its name from the way this part of a cell often looks like the letter X when seen under a microscope. That's why the name points to a special 'sex' chromosome that helps decide whether someone is 'male' or 'female'.
