The plant used in this experiment was Brassica Rapa which could be a Chinese cabbage but in our case was the Wisconsin Fast plants Wang et al. Wisconsin fast plants lab report.
This allows teachers to take a more inquiry student-centered approach.
Wisconsin fast plants lab. Wisconsin Fast Plants were developed as research tool at the University of Wisconsin Madison and have been used by K-16 teachers around the world for nearly 30 years as an educational model-organism. Wisconsin fast plants dihybrid cross lab report Follow these guidelines to write the lab report. Introduce Wisconsin fast plants.
Focus on their biological and genetics aspects. Introduce the basics of Mendelian genetics such as Mendels law of random segregation of gametes independent assortment of genes and linkage and mapping. The Effect of Artificial Selection on Wisconsin Fast Plants The purpose for performing this lab is to model artificial selection within Wisconsin Fast Plants.
As a class we chose the characteristic of average leaf length of the plants to be selected for in which a change in the average leaf length would be predicted in the offspring from the parent generation. In the lab you will grow wisconsin fast plants and record data on phenotypes. There are two parts to this lab.
Lab grades will be based on six short lab reports and four mastery quizzes. Not deceive yourself into thinking you know the answers by a quick visual. In this 3-week laboratory students investigate the effects of an abiotic or biotic ecological factor on the growth or reproduction of rapid-cycling brassica Brassica rapa L.
Wisconsin Fast Plants seedlings in the field. Measurable treatments include light wind herbivory chemical or organic fertilizer insecticides and growth regulators ie. In this 3-week laboratory students investigate the effects of an abiotic or biotic ecological factor on the growth or reproduction of rapid-cycling brassica Brassica rapa L.
Wisconsin Fast Plants seedlings in the fieldMeasurable treatments include light wind herbivory chemical or organic fertilizer insecticides and growth regulators ie gibberellic acid spray auxin paste. In the lab you will grow wisconsin fast plants and record data on phenotypes hypothesize the genotypes of the parents and use a chi square analysis to support or reject your hypothesis. Background Information Stem Color.
Anthocyanin is a purple pigment found in. The Wisconsin Fast Plants Program was originally created by Dr. Paul Williams and he was responsible for breeding these plants known as Brassica rapa.
He considered them to be a valuable research tool in that they could be used as means of disease control for a certain type of plant. Wisconsin fast plants lab report. Flats of the rapid-cycling Brassica plant are housed in a greenhouse run by Hedi Baxter Lauffer director of the Wisconsin Fast Plants Program.
Was developed for Sunset by Soil and Plant Laboratory Inc Bellevue WA. For this experiment consider using Wisconsin Fast Plants which. This experiment modeled the effects of artificial selection on the Wisconsin fast plants.
This experiment proved that what is expected to happen does not occur as we were expecting to see that parent generation and F1 generation were to be similar. There means as seen in the first and last figure are significantly different. For the first part of this investigation you and your classmates will perform one round of artificial selection on a population of Wisconsin Fast Plants.
First you will identify and quantify several traits that vary in the population and that you can quantify easily. Mendelian Genetics with Fast Plants by Jang Soo Lee. Mendelian Genetics Trait Types Trait changes in multiple generations Application of Punnett Square predictions Carolina Mendelian Genetics with Fast Plants Brassica rapa By DiscussionConclusion Chi-squared analysis determines the reliability of the.
In the lab you will grow Wisconsin fast plants and record data on phenotypes generate a hypothesis regarding the genotypes of the parents and use a chi square analysis to support or reject your hypothesis. Download PDF Google Doc. This lab is fairly easy to conduct though organizing the time frame can be challenging.
In order to carry out the experiment the class used the fast plants which contain strains ofBrassica Rapa. According to our lab manual it stated that the Brassica Rapa have a rapidbreeding cycle from seed to seed in 35 days. Due to their rapid breeding cycle plants in theBrassica family are ideal models for teaching and research.
In viewing the tapes of the student- suggested laboratory activities I finally saw. The purpose for performing this lab is to model artificial selection within Wisconsin Fast Plants. Rapa Wisconsin Fast Plant that you will be using has also been the subject.
Or other fast-growing plants. Salt Use road salt lab grade NaCl pickling or kosher salt. Transcript of Copy of Fast Plant Lab.
Wisconsin Fast Plants are used to assess the effects of plant growth on leaching. There are many factors which affect leaching soil depth soil texture plant type and density of plant growth are a few. This lab investigates the effects of soil type and plant presence or absence on nitrogen leaching.
Carolina is the exclusive distributor of Wisconsin Fast Plants. With Fast Plants you can see measurable changes in your plants each day. They have a super-.
An exciting aspect of this lab is that it can be employed using several different approaches. Wisconsin Fast Plants are designed to have short generation times with prolific seed production so several generations can be bred by students in a class over a few weeks. This allows teachers to take a more inquiry student-centered approach.
The plant used in this experiment was Brassica Rapa which could be a Chinese cabbage but in our case was the Wisconsin Fast plants Wang et al. These fast plants were used because just as the name states they are fast growing plants thus we could observe them better in a shorter period of time. Many lab investigations that help students derive an understanding of natural selection are either computer simulations or structured simulations.
However a promising alternative is to have the students study and carry out an artificial selection investigation using Wisconsin Fast Plants Brassica. Just as Darwin relied on examples. Wisconsin Fast Plants belong to the Mustard family Brassicaceae and have been genetically bred to complete their life cycle in approximately 1 month.
The students are asked to formulate a hypothesis and design an appropriate experiment to test their hypothesis. Students spend two 2-hour lab sessions on this project following a 20-30. These rapid cycling brassica or FAST PLANTS will.
Complete their life cycle in approximately 8 weeks. These lines were developed at the. We are going to examine genetic mutations that affect phenotypes in the.
Seedlings of these plants. You will be given. In Module 1 we used works genetic sciences of the Wisconsin Fast Plants Brassica rapa to analyze transmittal genetic sciences.
Brassica rapa was used since it is a theoretical account being. A theoretical account being possesses life rhythms and features that make them exceptionally suited for transmittal familial survey including a.
