Sir-Edward

Sir Edward is a very interesting turtle, since his coloration suggests that he is an Eastern box turtle (scientific name: Terrapene carolina carolina), while his back feet only have three toes, which means he might also be a three-toed box turtle (scientific name: Terrapene carolina triunguis or Terrapene mexicana triunguis), or possibly a mix (hybrid) between the two. If so, he might possibly be Albert‘s son, which would mean that Albert has been in the Riverside School courtyard for quite a long time, since Sir Edward is clearly an adult.

Another possibility is that Sir Edward came in to the courtyard from the outside, which means that he might be related to other turtles, such as Cutie, or Snickerdoodle, that were probably wild turtles from this area. To test this possibility, select Sir Edward on the first screen in the activity below, then select either Cutie as a mother, or Snickerdoodle as a father. Running this sort of test won’t prove that Cutie or Snickerdoodle are actually Sir Edward’s parents, but it will suggest that they are related if many microsatellites match.

Give the activity below a try (or several tries), and be sure to report your findings by answering the questions at the bottom! Oh, and if you aren’t sure what microsatellites are, click here.
