Fish Alleles

In class we tested the probability of different fish alleles and which would survive. There were three possible alleles: green, red, and yellow. Green was dominant which means if a fish has one green allele it will be green. Yellow and red are recessive to green, but are incompletely dominant to each other. This means they can mix to make orange. There were many green and orange fish because, green is always present and the red and yellow usually mixed.
Then we tested the environment, which was seaweed and algae, to see what fish would survive best. Normally the yellow fish died because they couldn't hide well in the 1st-3rd generations. Then at the end all of the algae and seaweed died, and the new surroundings hid all of the fish except the green ones. All of the green fish ended up dying. This completely wiped out all of the green alleles because if one is present it is showing. Below is a list of all of the fish through out the generations.

                        Green(GG,Gy,Gr)  Red(rr)  Yellow(yy)  Orange(ry)

1st Generation: 6                                 1         1                       4       Then all of the yellows died due to lack of camouflage 

2nd generation: 7                                 1         0                       3  

3rd generation:  6                                 2         1                       2      Yellows die again

4th generation:  5                                 3         0                       2     All of the seaweed and algae die which lets the other fish hide but wipes out all of the green fish

survivors:          0          3          0            2

If we had changed something such as the environment the outcome would have been different. Such as if they were in a different environment different fish would be able to hide better. If they lived in a sandy place yellow would do better, green in algae, red in dirt, or orange in coral. We could also have the fish adapt so the strong genes live but the weak die, over population, low food, or a different color fish could migrate over. We could also change the climate which would change type/number of fish and type/number of predators. There is a infinite list of things we could do to change the outcome.
