PPT-Chapter 12 Chromosomal Patterns of Inheritance

121 Chromosomal Inheritance 1 Genes are located on chromosomes this is called the chromosome theory of inheritance 121 Chromosomal Inheritance Chromosomes can be categorized as two types. This presentation . builds on session 1 exploring patterns of inheritance. Patterns of inheritance. The objectives of this presentation are to:. Understand how genes are inherited. Understand the differences between the inheritance patterns associated with Autosomal dominant, Autosomal recessive, X-linked recessive and chromosomal abnormalities. INTRODUCTION TO GENETICS. APPLIED GENETICS. Chapter 14A: INTRODUCTION TO GENETICS. Mendel. Rules and Terminology for Examination of Genetic Inheritance.
