Question

which ratios would indicate linkage and not independent assortment? check all that apply. 8:8:0:0 9:3:3:1 12:2:2:1

Explanation:

• In independent assortment, the phenotypic ratio for a dihybrid cross is \(9:3:3:1\).
• Linkage causes deviation from this \(9:3:3:1\) ratio. Ratios like \(8:8:0:0\) (where some phenotypes are absent or in very low proportion due to linked genes not assorting independently) and \(12:2:2:1\) (which is a non - Mendelian ratio indicating gene interaction influenced by linkage) show deviation from independent assortment.

Answer:

\(8:8:0:0\), \(12:2:2:1\)
