Title: Learning About Genetics
Description: This assignment is aimed at a high schoo level course and utilizes a website to help students answer questions about genetics. This material can be used as a source of study for a test.
Type of Task: Individual, Student-centered, Supplemental activity, Unsupervised
Time Required Set for two days but could be used as a one day assignment.
Topics: Homozygous, heterozygous, dominant, recessive, genotype, phenotype
Audience: High School
Categories:
Learning Objectives: Get students familiar with the terms we use when dealing with genetics. Also perpare the students for material they will need to know for exam purposes.
Text of Learning Exercise: Jeremy Tuttle
Web Based Instruction

This assignment is to be handed out by the teacher to every student. Students
should record their answers on this handout and return it to the teacher. This
