Answer: 2. Non-mendelian inheritance pattern

Key idea: Polygenic traits are controlled by many genes, each with a small additive effect, and give continuous variation.

They do not show a simple dominant-recessive pattern, so the official answer is non-Mendelian. Autosomal dominant and X-linked recessive are single-gene patterns.
