Product Details

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. An excellent experiment to serve as a starting point for a more in-depth examination of this continuing question.

Complete for 30 students working in pairs.

Performance Expectations

HS-LS3-1. Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring.
HS-LS3-3. Apply concepts of statistics and probability to explain the variation and distribution of expressed traits in a population.
MS-LS1-4. Use argument based on empirical evidence and scientific reasoning to support an explanation for how characteristic animal behaviors and specialized plant structures affect the probability of successful reproduction of animals and plants respectively
MS-LS1-5. Construct a scientific explanation based on evidence for how environmental and genetic factors influence the growth of organisms.
MS-LS3-2. Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation.
