Allen’s rule states that,

#Unit 10. Ecological Principles
  1. among closely related endothermic (warm-blooded) vertebrates, those living in colder environments tend to have shorter appendages than those living in warmer environments.
  2. High temperatures are also limiting for many plants and animals
  3. Many organisms cope with heat stress by producing increased amounts of heat shock proteins (HSPs).
  4. Those species in colder, arctic environments have shorter ears than those in temperate or hot desert environments

#Unit 8. Inheritance Biology

You identify a previously unidentified plant species and decide to study its genetics. You establish true breeding strains for leaf shape (longer than wide vs equal length and width) and flower color (white vs. yellow). When you perform a dihybrid cross with these strains, you find that your results are very different than those predicted by a 9:3:3:1 ratio. You calculate a chi square and get a p value of less than 0.0001. Which of the following statements is most accurate based on this observation?
