What linkage means in Biology A-Level, as defined for AQA.
Definition of linkage
Check what you remember
Read the wording for your board, then hide it and explain linkage in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Genes at different loci on the same chromosome tending to be inherited together rather than assorting independently, with closer loci giving stronger linkage.
