Chapter 9: Patterns of inheritance Patterns of inheritance have been observed for many years. The chapter defines heredity as the transmission of traits from one generation to the next and genetics as the scientific study of heredity. The first person to analyze these patterns of inheritance is Gregor Mendel who worked in the 1860s. Mendel’s law of independent assortment states that the inheritance of one character has no effect on the inheritance of the other. The chapter further gives a definition of recessive and dominant genes (Simon, Dickey and Reece).
Chapter 10: Structure and function the of DNA
DNA is known as the chemical in a cell by end of the nineteenth century. It has a capacity to store genetics information and can be passed from one generation to the other. It is made up of chemical units called nucleotides. When a change in the nucleotide sequence of DNA occurs, this is referred to as mutation (Simon, Dickey and Reece).
Chapter 12: DNA TECHNOLOGY
DNA technology has to advances in the creation of genetically modified crops as well as the identification and treatment of genetic diseases. Bio Technology – is the manipulation of organisms or their component to make useful products. It has been in use for many years in the making of breeds using yeast and selectively bred livestock for desired traits. The technology is also used in the production of valuable molecules like vaccines (Simon, Dickey and Reece).
Chapter 13: How populations evolve
Charles Darwin proposed a hypothesis for his observations. In his book, he describes the evidence supporting his hypothesis. He hypothesized that present day species descend from ancient ancestors that they still resemble in some ways. Natural selection I defined as the process in which organisms with different characteristics are more likely to survive than individuals having other characteristics. Natural selection leads to evolution (Simon, Dickey and Reece).
