Lesson Plan: Sex and Autosomal Linkage Biology • First Year of Secondary School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to identify sex-linked traits and explain how autosomal linkage impacts inheritance of genes.
Objectives
Students will be able to
- give examples of sex-linked traits including color blindness and hemophilia,
- interpret genetic diagrams displaying inheritance of these traits,
- distinguish between sex-linked, sex-influenced, and sex-limited traits,
- describe and explain autosomal linkage,
- analyze genetic diagrams that demonstrate the sex-linked inheritance (e.g., inheritance of eye color in Drosophila, as shown by Thomas Morgan).
Prerequisites
Students should already be familiar with
- chromosomes carrying genetic material,
- using simple Punnett squares.
Exclusions
Students will not cover
- epistasis.
