Feature

Develop a controlled experiment and collect data from self and family members
Understand and demonstrate principles of heredity and the relationship of dominant and recessive traits
Construct a family tree for a single trait in their family
The experiment is based on the transmission of a single inherited trait - the ability to taste harmless PTC (phenylthiocarbamide)
Good for up to 50 students, depending upon how many family members are tested

Description

The experiment is based on the transmission of a single inherited trait - the ability to taste harmless PTC (phenylthiocarbamide). The goal is for students to determine if they have this gene. They collect data by testing family members, correlating and pooling the data for the entire class, then calculating the random segregation data according to the Hardy-Weinberg Law. Background information about the Hardy- Weinberg Law and information about calculating gene frequency and the genetics of ABO blood typing are included. Kit includes Teachers guide with MSDS (1), strips, PTC test paper (50), strips, control test paper (50), genealogy and data charts (50).
