Punnett Squares and Sex-Linked Traits Amoeba Sisters Handout

This Punnett Squares and Sex-Linked Traits Amoeba Sisters handout was made to accompany the Sex-Linked Traits and Punnett Squares video made by the Amoeba Sisters on YouTube.

In this video, students will explore how sex-linked traits are inherited, why X and Y chromosomes matter, how to represent alleles with superscripts, and how to solve Punnett squares to predict carriers and affected offspring.

This is not your average video worksheet!

My worksheets are designed to include:

• An anticipation activity to access prior knowledge and spark engagement
• Multiple choice questions in order of the video (not too slow or too fast)
• An independent activity for student practice after the video
• A fun extension activity
