Read the wording for your board, then hide it and explain Autosomal linkage in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Genes linked on the same autosome tend to be inherited together, so the ratio departs from 9:3:3:1 with an excess of the two parental phenotypes and fewer recombinant types.
