Inheritance and Genetics: Observing Variation and Measuring Selection in Fast Plants

Variation is a fundamental attribute of life; understanding its nature is important to all. Wisconsin Fast Plants are an ideal model for teaching this concept, with easily observable variation in many plant traits. This variation can be observed, described, and measured or quantified to gain greater understanding of plant traits. Development of selection experiments allows analysis of recorded data and measuring …

Counting Leaf Hairs on Fast Plants for Selection Experiments

Hairs are not often a trait that we associate with plants. However, of all the traits that students might observe in a population of Fast Plants, we can learn a lot about variation and natural selection by counting and selecting for the number of hairs on a leaf margin. Selective breeding to increase (or decrease) hairiness can provide an excellent opportunity …
