Artificial Selection Investigation

Information

Artificial Selection Investigation

This group includes our Science House Interns: McKaylee, Jackson, and Cherie (pictured) who are growing out ~100 Standard Fast Plants and gathering data on this population that will be used to select for a particular trait with the goal of increasing the frequency of that trait in the next generation.

Location: Science House, UW-Madison
Members: 8
Latest Activity: Aug 3, 2013

​Can we selectively breed for a particular trait​ expression and cause an increase in its frequency in the next generation?

Our procedure is derived from the new AP Biology lab, and a simple "calendar" outlining the steps we are following can be found in the Fast Plants Digital Library.

In this group's Discussion Forum, we've started a Discussion for each day during the investigation when we recorded data, made a significant decision or realization about our procedures, or developed new questions.

We are using an iPad to take photos and record observations and measurements. Included in the Discussion Forum are pictures of our plants and data; we welcome your comments and questions.

We initially planted in 32 quads and thinned the multiple plants that grew down to one per cell, leaving us with 128 plants. We selected these by which ones grew closer to the middle of the cell, and removed those closer to the edges.We have been…Continue
