Why is it Parametre değerleri and not Parametrenin değerleri?

In Turkish you can create a noun‐noun compound by placing two nouns side by side, without any case or possessive ending on the first noun.
• Parametre değerleri = parameter values in a general, descriptive sense.
• Parametrenin değerleri = the values of the (specific) parameter, using genitive (-in) + possessive (-i) for a definite relationship.
