The "Toothpick Fish" are a special kind of fish that adapt and change colors at the time of need. In order for them to "adjust" to the settings, we came to help and decided to pick out two toothpicks to determine the scale colors they would receive. We were the fate of their lives. Before I could go on any further for this lab, the most important info I need to know is that the green allele (G) is dominant to all the other alleles, the red allele (r) is recessive to green and incompletely dominant to yellow,and that the yellow allele (y) is recessive to green and incompletely. With this amount of data, the genotypes were destined to be made.
Here's a "chart" of the possible genotypes and phenotypes.
Phenotype | Genotype
--------------------------
Green | GG, Gr, Gy
Red | rr
Yellow | yy
Orange | ry
There are twelve fish at the start each varying in color. Each of them go through the battle of survival. The environment changes through the generations ranging from seaweed and algae to a empty river full of rocks and sand. These fish will have to go through four generations of pain and terror. Wish them luck as death has come to gobble them. RAWR 0-0...
The Game of Survival
Round 1
The battle for life has began and the fish are about to enter in the first generation. As my partner and me place our hand inside the clear plastic cup controlling fate, our offspring had first came out as yellow. Success! This could be the start of something revolutionary. However, it became depressing as the yellow fish had become the one oddball. In the end of generation one, green had seven whooping fish on its side while orange had four. Yellow only had one and red was nowhere to be seen. Six of the green fish had been heterozygous dominant while one of them was homozygous. The orange had naturally been co-dominant with the yellow and red while yellow was born the way it was. Sadly, the yellow had not been able to fit in with the algae surroundings in the lake we put the fish in. The yellow species had died out for now...
X= dead
Results of First Generation:
1 |yy | yellow X
2 |ry | orange
3 |ry |orange
4 |GG |green
5 |ry |orange
6 |Gr |green
7 |Gy |green
8 |ry |orange
9 |Gr |green
10 |Gy |green
11 |Gr |green
12 |Gr |green
Round Two:
Generation two has come and a new batch of freshly bred fish has been mated. It seems that the green population has decreased to six fish. There is only one red fish left and the orange fish population has stayed the same. The alleles has changed and now seven yellow genes remain. Maybe it could be the start of a revolution? The algae still remains and nothing exciting happens in this generation.
Results from second Generation:
Offspring | Genes| Color|
1 |GG | green
2 |Gy | green
3 |GG |green
4 |ry |orange
5 |Gr |green
6 |ry |orange
7 |Gr |green
8 |Gy |green
9 |ry |orange
10 |ry |orange
11 |rr | red
Round Three:
Nothing changes in this round. All the fish remain alive with their new look. It still seems all the fish are going for the green bandwagon. Ten green fish now live in harmony while one red stays the same. Eight green fish are heterozygous dominant, with four of them having the yellow allele in them. The other two are part red.
The results are not being made due to the "screen not working".
Round 4.
DISASTER STRIKE. A factory waste harms the algae and it all disappears. Rocks are only left in the pond... Only the one red fish survive and two orange fish are able to hide. Everyone else dies. Only three fish remain. Let us remember them in peace...
