Imagine you are a scientist observing rats in the wild. As the rats reproduce, rats born with white fur slowly begin to outnumber rats with black fur. In three to five sentences, provide two or more different explanations of why the rats with white fur might be outnumbering the rats with black fur. Write it like a 7th grader would.
One reason why rats with white fur might be outnumbering rats with black fur is because the white fur helps them blend in better with their surroundings, making it harder for predators to spot them. This means that white rats are more likely to survive and have babies, passing on the genes for white fur. Another reason could be that the white fur gene is dominant over the black fur gene, so more baby rats end up with white fur.
