    Academic text (2018)
  • However, linkage analysis is largely limited by its reliance on prior knowledge of disease pathophysiology.

    Academic text (2018)

Morphology

linkage = link (semi-transparent) = link + age

The word is morphologically clear, but the genetics sense is a technical specialization that is not obvious for many learners.

Etymology

Linkage comes from link ('a connection') and -age ('a result or thing'), so in genetics it means genes that are 'connected' on the same chromosome and tend to be inherited together.
