Agriscience Lesson 12: Creating a Wooly Booger

In this experiment, students will study the genetics of quantitatively inherited traits by examining the concepts behind a selective breeding program designed to encourage certain characteristics.

Two populations of Wisconsin Fast Plants -very hairy and few to no hairs- will help them determine the heritability of the trait and the results of a selective selection. In the first part of the experiment, students will strive to create a population of intermediate hairiness and in the second part, they will strive to create a very hairy plant, the Wooly Booger.

This experiment may be terminated at any generation. However, one may find that the data and seed from the crosses may be carried from year to year as a continuous test for your school.

NGSS Standard	NGSS.HS.LS4.4 Construct an explanation based on evidence for how natural selection leads to adaptation of populations. [Clarification Statement: Emphasis is on using data to provide evidence for how specific biotic and abiotic differences in ecosystems (such as ranges of seasonal temperature, long-term climate change, acidity, light, geographic barriers, or evolution of other organisms) contribute to a change in gene frequency over time, leading to adaptation of populations.] NGSS.MS.LS4.6 Use mathematical representations to support explanations of how natural selection may lead to increases and decreases of specific traits in populations over time. [Clarification Statement: Emphasis is on using mathematical models, probability statements, and proportional reasoning to support explanations of trends in changes to populations over time.] [Assessment Boundary: Assessment does not include Hardy Weinberg calculations.]
