GENETICS: INHERITANCES & BIOTECHNOLOGY
Genetics of Taste
Why are some people very sensitive to
the taste of spicy food while others are
not? Is this taste sensitivity inherited? This laboratory activity will explore whether the ability to taste various substances is genetic. Students will be involved in collecting class and family data to determine the genetics of PTC tasting. Taste tests for other substances will illustrate the complexity of the genetics of tasting. Includes worksheets, complete teaching directions and over 400 taste test strips. Complete for 30 students working individually. Super Value Kit is complete for 5 classes of 30 students working individually.

Why Do People Look Different?
Simultaneously teach electrophoresis and DNA fingerprinting. Students determine what members of a family look like by running simulated DNA samples in agarose gel. Traits investigated include hair color, eye color, and the presence or absence of freckles. Includes agarose, buffer needle- tip pipets, five simulated DNA samples, complete instructions and student work- sheets. Complete for 6 student groups. Super Value Kit is complete for 30 student groups. Requires electrophoresis apparatus and power supply.

Heredity and Environment—

Which is more important—heredity or environment? Students investigate this age-old question using albino tobacco seeds from heterozygous parents—ones that should produce a ratio of three green for every one albino tobacco plant. Some seeds are germinated in the light, and others are germinated in the dark. The environments are then switched. After reversal, the ratios change and students must use their data to defend which is more important— heredity or environment. Complete for 30 students working in pairs.

Student Laboratory Kit
Genetically Modified Food—
Student Laboratory Kit
Your students will gain insight into genetically modified food as they compare the growth of traditional soybean seeds with seeds that have been genetically modified to withstand the effects of a widely used herbicide. What are the advantages to the soybean farmer? This hands-on activity will provide firsthand experience with transgenic crops and serve as a basis to do further study and research on this timely topic. Includes student and teacher materials, soybean seeds, pots, soil, herbicide and all other necessary materials. Complete for 30 students working in pairs. FB1594 | $57.65
Six-Gel Electrophoresis Apparatus
This oversized, seamless, injection-molded tank is safe and easy to use. The lid is transparent for clear monitoring of the run and features two push tabs for easy assembly and removal. The platinum-coated electrodes are removable, and the leads are safety coated and recessed into the lid. Apparatus includes six removable and adjustable leveling feet trays. Requires power supply, such as FB0316.
