Question

You observe continuous variation in tail length in a wild population of rats. Describe an experiment to determine whether this variation is an example of variable expressivity or continuous variation?

Answer 1

When you grab a wild population of rats, you need to follow the scientific method as it is, and by doing that, you can discover if it is a variable expressivity or a continuous variation.

Step-by-step explanation:

First, you need to check the species, to see their patterns of length of tail, because that's mostly what you want to know. After stablishing this pattern, you'll check the variability of their variation on different generations. For example, you pick up a rat that is aged a month, and a rat that is aged 3 months, and then compare them to one another. After you've done this lots of times, you can check if this variable is just a random one, or if it is continuous throughout the generations.
