My rating of this resource: ***

My experience using this resource:

Genetics

Topic I was teaching:

independent assortment of chromosomes

My learning goal for which this resource was used:

I wanted students to have a visualiztion of huge variety of gamest that can be produced with a 2n=46 chromosome number. They can see indpendent assortment easily when 2n=4, but this breaks down a little bit when I ask them to visualize 2n=46 (i.e. a human cell).

Course Level:

Honors or Advanced, Intro or Regular, Remedial

How I/my students used the resource:

After we discussed indepedent assortment we watched the animation in class.

Value Added:

Provides visualization or animation

Strengths:

It quickly reviews the number of gamte combinations that could result with a 2n=2. The text that accompanies the animation is good quality. The animation does a great job toward the end showing the variety of gametes a dipliod cell is capable of producing by meiosis. This is the best part of the animation because students can see one combination, but can easily imagine other possibilities. It makes the number of 2^23 (8,388,608) seem more impressive but also more plausible.

Weaknesses:

I wish it also showes the mothers gemone going through the same process. Then it would be great to see these two gametes fusing to form offspring.
