Genetics has a lot of specific terminology, and I wanted to help it be a little more memorable and accessible, so we used cartoon aliens instead of peas and put a strict limit on the number of new words we introduced in the video, which had me dancing around not using "allele"... but, on the whole I think it came together well.

I made a simple worksheet to go along with it (aimed at age 8 to 10 years old), and Math Dad put together a series of Desmos activities, which are targeted more for middle-school/high school age. The teacher dashboard to launch those is here: https://teacher.desmos.com/activitybuilder/custom/5bd68d7b709236479c3fcbbe
Worksheet is attached just below. Enjoy!
