Jul 11, 2023 · In the following chart, label the gene on each chromosome in each type of zygote that could be produced by a mating between this mother and father. Then, fill in the genotypes of the baby dragons that result from each zygote and sketch in the characteristics of each baby dragon to show the phenotype for each genotype.

1. A DNA model 2. A picture of a chromosome
For each student
1. A set of chromosome strips in two colours (14 pink strips for the mother and 14 blue strips for the father) 2. A student worksheet 3. Crayons (at least four colours) The chromosome strips, Tables 1-3 from the worksheet, the worksheet itself and the basic dragon drawing can be downloaded from the Science in School websitew1.
Using the information below, introduce the dragon story and the required background for the activity to the students. Then hand out the materials and let the students follow the instructions on the student worksheet. Tables 1–3 can also be downloaded from the Science in School websitew1.
Dragons are a curious type of creature. Amazingly, though, their genetics is very similar to that of humans – or even guinea pigs. Many schools keep pet guinea pigs, but wouldn’t it be much more exciting to keep a herd of dragons? Unfortunately, dragons are very expensive, so your school can only afford two – one of each sex. The purpose of this ac...
Each cell in all living organisms contains hereditary information that is encoded by a molecule called deoxyribonucleic acid (DNA): show students the DNA model. DNA is an extremely long and skinny molecule, which when all coiled up and bunched together, is called a chromosome: show students the picture of a chromosome. Each chromosome is a separate...
Codominance
To introduce the concept of codominance, you can extend the activity by swapping the relevant materials concerning the body colour trait (genotype Aa) for the following ones with the genotypes A/Ä/a, where A and Ä are codominant and a is recessive: You will need to replace the A/a chromosome stripes by two different sets of parents to achieve offspring with all six possible genotypes. Half of your class should get set 1, the other half set 2.
Instead of drawing dragon parts, you could have your students draw other mythical creatures, or even build them, for example from marshmallows and pins (see Soderberg, 1992).
This activity is based on an idea by Patti Soderberg, adapted with permission from The Science Teacher (see Soderberg, 1992). Her reebops lesson was then adapted by the authors. Credit for the chromosome strips goes to Nancy Clarkw2, and Marlene Rau, editor of Science in School, included the codominance example.

In this activity, you and a partner will work together to produce a baby dragon. You will simulate meiosis and fertilization, the biological processes by which the parents' genes are passed on to a baby.
