I recently did a lab in science class, and the results I came up were very interesting. We had three fish of diffrent colors that all lived in a pond near a waste factory. ( Fish colors: red,green, yellow) The dominant alleles were green, while the yellow and red alleles were ressecive. When we paired up the fish, their genotypes showed that most of them were green, but the yellow ones died because they wern't camoflauged well enough in the pond that was filled with green algae. ( The red fish could hide easily) For every generation, I took out the yellow fish because they were eaten. When I got to the 4th generation, there was a natural disaster and all the green fish died. When the natural disaster happened, the population of the fish was just wiped out. The physical characteristics of the green fish gave them away, because all the green algae died from the toxic waste that was dumped into the pond. Accidents like this could be avoided in real life life we didn't build factories near wild life areas. As I said before, the population was just wiped out. Depending on the ecosystem, it may not be be just plants that die but animals too. We should pick good places before building things that are harmful to the environment like factories.
( We used colored toothpicks to do this lab, and no animals or plants were injured while doing this lab. This situation was fictional and did not happen, but the concern is serious.)
