How many pairs of chromosomes?

Submitted by iwaldron on Thu, 10/01/2020 - 11:32am.

Thank you for your comment. As always in teaching, each of us needs to balance competing priorities. In question 18 concerning independent assortment, we show two pairs of homologous chromosomes to illustrate the locations of the defined genes on two identified human chromosomes. I chose this approach because it helps students to understand the whole point of chromosomes and meiosis, and it would be unduly complicated to include a third pair of chromosomes with another gene. I recognize that other teachers will have different priorities which perhaps could be accommodated by editing the word version or Google doc of the Student Handout.
