Analyzing the Effects of the Environment on Traits Student Guide Purpose In this assignment, you will apply concepts of statistics and probability to answer questions about how environmental factors affect the variation and distribution of expressed traits in a population. Background Information Genetic and environmental factors affect which traits are passed on from parent to offspring over generations and how they are passed on.
