Purpose
This experiment served to clarify the relationship between dominant and recessive genes, while also furthering my understanding of the changes caused by mutation at a biochemical level using a computer model.
Methods/Results
- The program title Aipotu version 1.3.3 was downloaded.
- In order to decipher the color of the alleles present in the default Greenhouse the following crosses were performed:
| Organisms Crossed | Resulting Colors | Alleles Involved | |
|---|---|---|---|
| Green-1 x Green-1 | green | Cg | |
| Green-1 x Green-2 | green | Cg, Cx | |
| Green-1 x Red | green & black | Cg, Cr | |
| Green-1 x White | green | Cg, Cw | |
| Green-2 x Green-2 | green, blue, & yellow | Cb, Cy | |
| Green-2 x Red | blue, yellow, orange, & purple | Cb, Cy, Cr | |
| Green-2 x White | blue & yellow | Cb & Cy | |
| Red x White | red & white | Cr, Cw |
How many different alleles are there? Which colors do they produce?
| Alleles | Color |
|---|---|
| CwCw | white |
| CyCy | yellow |
| CgCg | green |
| CbCb | blue |
| CrCr | red |
Which are dominant and which are recessive?
Dominant- Blue, Red, Green
Recessive- Yellow, White
How do the colors combine to produce an overall color?
| Genotype | Phyenotype |
|---|---|
| CgCr | black |
| CbCr | purple |
| CyCr | orange |
| CwCw | white |
| CyCy | yellow |
| CgCg | green |
| CbCb | blue |
| CrCr | red |
Using the symbols you have developed, give the genotypes of the four starting organisms.
| Organism | Genotype |
|---|---|
| Green-1 | CgCg |
| Green-2 | CgCr |
| Red | CrCw |
| White | CwCw |
Using this knowledge, construct a purple flower.
Cross Green-2 and Red
Can you construct a pure-breeding purple flower with the starting set of organisms?
No because purple occurs due to red and blue co-dominance.
