Examining alleles of fishes can be very important when they are able to adapt to their surroundings by camouflage. To begin off the first generation in the gene pool contained of two heterozygous pairs of green and red fish, two homozygous pairs of yellow fish, one homozygous red, four orange, and three homozygous green fish. When all these fish mated they produced offspring equaling to 58.3% green, 16.6% red, 16.6% yellow, and 8.3% orange. Since the yellow fish could not adapt to the gene pool, they died going in the morgue, which decreased the population by 16.6%. During the second generation of offspring there were 50% green, 20% red, 0% yellow, and 30% orange. Then during the third generation the total color of offspring was 60% green, 20% red, 10% yellow, and 10% orange. And lastly, the fourth generation contained of 55.5% green fish, 33.3% red fish, 0 yellow fish and lastly 11.1% orange fish. As you can see all the colored fishes have decreased except for the green fish. This happened because the green fish was dominant making its population increase.
During the fourth generation a huge disaster occurred. Humans started littering the gene pool, causing the seaweed and algae to turn different colors. Now that the seaweed and algae have changed colors the green fish are easily able to be seen and eaten by their predators, while on the other hand the red, yellow, and orange fish are able to camouflage by sand and rocks. Now the only survivors are red fish and yellow fish. There are 11.1% orange fish and 33.3% red fish remaining. This disaster shows that by humans polluting the earth they can cause the dead of many organisms. If the environment changed in any way, it could change the way fish live, by the fish adapting to the environment. For example, if the littering human did to the gene pool destroyed seaweed and killed algae many fish could die including the green fish. As you can see many fish adapt and survive by camouflaging while others easily spotted by their predators.
