Question

Imagine 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 3 to 5 sentences provide two or more different explanations of why the rats with white fur might be outnumbering the rats with black fur

Answer 1

One possible explanation for the increase in white fur rats could be related to climate change. If the environment is becoming warmer, white fur may provide better camouflage in snow-covered or light-colored surroundings, giving the white fur rats a survival advantage. Another explanation could be genetic drift, where random fluctuations in allele frequencies over time can lead to certain traits becoming more prevalent in a population. Alternatively, there may be a gene linked to white fur that also provides a fitness advantage, such as resistance to certain diseases or improved access to food sources.
