- 1 How many different alleles are there? Which colors do they produce?
- 2 Which are dominant and which are recessive?
- 3 How do the colors combine to produce an overall color? For this, it may help to make a genotype-phenotype table and then try to abstract rules from that. You should be sure that you have tried all the possible combinations of the alleles you found in part (a).
- 4 Using the symbols you have developed, give the genotypes of the four starting organisms.
- 5 Using this knowledge, construct a purple flower.
- 6 Can you construct a pure-breeding purple flower with the starting set of organisms?
- 7 Post your findings to your section’s Lab Data Blog.
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? For this, it may help to make a genotype-phenotype table and then try to abstract rules from that. You should be sure that you have tried all the possible combinations of the alleles you found in part (a).
| 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.
