What is Turner’s syndrome? • A genetic disorder which only affects and occurs in females • It is a result of only one X chromosome present in the gamete (monosomy X ) • T.S can also occur if one of the sex chromosomes is partly missing or rearranged • This missing chromosome is responsible for the developmental affects • There is an extremely small chance of the fetus actually surviving How is a person diagnosed? • A person can be diagnosed by taking a sample of blood‚ amniotic fluid or

Evolution Unit: Objectives AP Biology Upon the completion of the textbook readings in Chapters 22-26 you should be able to: Chapter 22 1. Explain how the principle of gradualism and Charles Lyell’s theory of uniformitarianism influenced Darwin’s ideas about evolution. The basic idea of natural selection is that a population of organisms can change over the generations if individuals having certain heritable traits leave more offspring than other individuals. The result of natural selection
