In this activity, students use the free app "Gene Screen" to answer a series of questions. Your students should be familiar with the terms homozygous, heterozygous, gene, trait, and carrier before using this app since those words are mentioned frequently throughout the webquest.
The app focuses primarily on inherited genetic diseases such as Tay-Sachs, Cystic Fibrosis, and even Maple Syrup Urine Disease. I've made the worksheet to be student-paced and not teacher directed. This could easily be assigned as homework or even as sub plans.
The entire document is in Word to make editing possible. Thanks!
