#Unit 8. Inheritance Biology

  1. Within a wild population of clover plants, there is a very low amount of variation in the number of leaves per stem.

  2. When studying obesity in a human population, there tends to be less variation within families than across the entire population.

  3. in a study of adopted children, the children's height is much more similar to that of their biological parents than their adoptive parents.

  4. The DNR maintains records of deer shot each hunting season. In drought years, the average weight is much lower than in years of sufficient rain.
