How Hemophilia is Passed On

In 2009, I was asked to speak in a high school biology class, and made a Flash presentation to show how Hemophilia is passed on as a visual aid.

The file will open in a Flash Player window. Yes, I know Flash is antiquated and deemed insecure but I haven't been able to find my original .fla file (it's probably on one of the many hard drives I have stored in my cabinet) to update it.

How Hemophilia is passed on
The red and blue XYs are normal genes and the green Xs are hemophilia tainted genes. In case you aren't into biology...the XY is a male and the XX is a female. You can progress through the presentation by pressing the "Continue" button.
Below is a legend of what is shown in the presentation:
  • Red X, Blue Y = Male, Not Affected by Hemophilia
  • Red X, Green X = Female, Carrying Hemophilia
  • Two Red Xs = Female, Not Affected by Hemophilia
  • Green X, Blue Y = Male, Hemophiliac
