Purpose
The purpose of these investigations was to examine color inheritance in flowers as well as seeing the effects of mutations on color, protein sequence, and DNA sequence.
Methods/Results
I. Genetics - Crosses
- Cross two organisms.
- Cross Green-1 and White using the "Cross Two Organisms" buttons in the Upper and Lower Work Panels after selection.
- After crossing two organisms, the offspring is saved in the History List as a Tray.
- Self-Cross a single organism
- Select an organism from Tray 1 and click on "Self-Cross One Organism". The offspring will be displayed in the Lower Work Panel.
- If an organism seems interesting, save it to Greenhouse:
- Click "Add..." at the top of the Greenhouse
- Give the organism a name and select "Save Greenhouse"
Questions:
| Allele | Color | Dominance |
|---|---|---|
| Cg | Green | Dominant |
| Cr | Red | Dominant |
| Cw | White | Recessive |
| Cy | Yellow | Dominant |
| Cb | Blue | Dominant |
| Genotype | Phenotype |
|---|---|
| CgCg and CgCb | Green |
| CgCy and CgCw | Green |
| CwCw | White |
| CyCw | Yellow |
| CbCb and CbCw | Blue |
| CrCw | Red |
| CgCr | Black |
| CyCo | Orange |
| CrCb | Purple |
What rules can you find to explain the data above?
- From the data, the rule of dominance can be applied. In the presence of a dominant gene, the dominant phenotype is expressed in both a homozygous dominant and a recessive gene. In some instances, a color is produced that isn't solely made on its own such as black. In that instance, there is codominance occuring between the genes. If two genes are codominant, there will be an intermediate color such as black due to the cross between red and green genes.
What are the genotypes of the starting strains?
- Green-1: CgCg
- Green-2: CgCy and CgCw and CgCb
- Red: CrCw
- White: CwCw
Why is the flower purple?
- The purple flower occurs when there is a cross between red and blue. The resulting purple color comes from the incomplete dominance of the two strains. Purple cannot be created without these two alleles because it is a mixture between the two colors.
Can you construct a pure-breeding purple flower using only the four starting strains?
- You can construct a purple flower using Green-2 and red. This is because the Green-2 strain is made up of blue alleles which is another allele for the cross in making the purple flower.
II. Genetics - Mutation
- Mutate any one organism
- Make a pure-breeding strain of a color and note it.
- Select a pure-breeding organism and click on "Mutate One Organism".
- An organism of a different color should appear. If not, keep mutating the strain until one appears.
- Save the mutant organism and name it.
- Figure out how the mutation changed the Protein Sequence:
- Click on the Biochemistry tab.
- Double click on the saved mutated organism
- From the Compare menu, choose Upper vs Lower to compare the two amino acid sequences and make note of the difference
- Figure out how the mutation changed the DNA Sequence:
- Click on the Molecular Biology Tab.
- Double Click on the organism that was saved.
- Compare them both using Upper vs Lower in the Compare menu. Make a note of the difference in the DNA sequence.
- Create a Journal Entry with the Data:
- Include:
- The starting color and final color
- The change in protein sequence
- The change in DNA sequence
- Attach the organism file in the Journal to store it for later
- Include:
