A snake does not have legs. Nevertheless, it has tiny hip-like bones in its midsection where legs could reasonably attach. The bones have no function. How do the hip bones of a snake provide evidence for the evolution of snakes? A. The hip bones are vestigial structures that show evolutionary descent from an ancestor that had legs. B. The hip bones are analogous structures with the leg bones of other animals, and show how they all evolved from a common ancestor. C. The hip bones are vestigial structures that show that snakes, worms, and other legless animals evolved by adaptive radiation. D. The hip bones are homologous structures with the vertebrae and other bones of the snake, and show the sequence in which the vertebrate skeleton evolved.

Chapter 11.1 & 11.2 notes section 11.1 1. every living thing has a set of ? inherited from its parents. 2. after becoming a ? , mendel spent several years studying ? and mathematics at the university of vienna. 3. during sexual reproduction, male and female reproductive cells join, a process known as ? . 4. pea flowers are normally ? , which means that sperm cells in pollen fertilize the egg cells in the ? flowers. 5. when mendel crossed plants with ? characters for the same trait, the resulting offspring had only one of the characters. 6. a ? is a specific characteristic, such as seed color or plant height, that varies from one individual to another. 7. filius and filia are the latin words for ? and ? . 8. the offspring of crosses between parents with different traits are called ? . 9.to mendel's surprise, all of the offspring had the character of only ? of the parents. 10. mendel's first conclusion was that biological inheritance is determined by ? that are ? from one generation to the next. 11. scientist calls the chemical factors that determine traits ? . 12. mendel's second conclusion is the ? . 13. the principle of dominance states that some alleles are ? and others are ? . 14. when mendel allowed the f1 plants to reproduce by self-pollination the traits controlled by ? alleles reappeared in about ? of the f2 plants in each cross.
