This is a lab/activity that uses dragons as "research subjects" for genetics research. It highlights
independent assortment as well as gene linkage. Students will do the first part of the activity using
independent assortment (genes on different chromosomes). The second part of the activity looks at
genes on the same chromosome, and how linkage plays a part in allele assortment. It can be used to
show how crossing over allows increased variation when involving linked genes.
Worksheets are available in both Word and PDF formats, for both teacher and student. There is an
additional dragon genetics lab that illustrates the principles of Mendelian genetics as a whole.

PUBLIC REMARKS
By Author/Submitter
This activity is very interesting to the students since it deals with dragons instead of the classic
flower examples we use. It is an excellent activity to show independent assortment and linkage in a
way students will understand. It will engage all levels of learners, and can be used as a cooperative
learning activity.
By Reviewer 1
There are good activities but I would break them up into smaller lessons for students at or below
grade level.
By Reviewer 2
Great resource, may require smaller segments for lower level learners.
