Question

A population of fuzzy-wumpkins differ in how fuzzy their fur is. Populations in cold climates are fuzzier than in warm climates. Fuzzy-wumpkins mate for life.
You transplant a reproductive pair of fuzzy-wumpkins from a warm climate into a cold climate, and a second pair from the cold climate into the warm climate. As a control you also transplant a reproductive pair from warm climate back to the warm climate and from the cold climate back to the cold climate. You then measure the fuzziness of the fur of offspring that were produced by each pair.

Part A: If the fuzziness trait had a strong genetic component (e.g. high heritability) what pattern would you find between parent fuzziness and offspring fuzziness.
