Based on the results of the mouse coloration case study, suggest another hypothesis researchers
stiv31 [10]

Answer:

Please see below

Explanation:

With the study on coat color, mice who could blend in better in the environment would be less likely to be detected bu the predator. Another hypothesis could be made in relevance to their legs. Longer legs would help the mice run quicker and increase the chances of escaping from the grasp of the predator, and hence, make survival more likely so it will be selected for. While shorter legged mice will be selected against since they are at a disadvantage.
