PPT-Multiple Alleles and Sex-Linked Patterns of Inheritance

Multiple alleles a gene inheritance pattern in which at least three unique alleles are present for one trait the three alleles may interact with each other using any other pattern DominantRecessive Incomplete Dominance Codominance etc. 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. Expanding the Rules and Terminology to follow two (or more) genes in a cross. What you should know:. The ‘etiquette’ used to represent genetic crosses.. Know what is, and how to represent a monohybrid cross.. Know what is, and how to represent a cross showing sex-linkage.. Kyle . Stutts. . Sam . houston. state . university. Sex-Linked Characteristics. Objectives. Students will be able to:. Comprehend how inheritance plays a role in sex-linked genes. Explain the difference between sex- linked, limited, and influenced inheritance. SBI3U. Mendel Demonstrated. :. Law of Segregation. Law of Independent Assortment. The . alleles. for a gene . segregate independently. . during meiosis. . This applies to alleles located on homologous chromosomes. Multiple Inheritance. A subclass can inherit from multiple . superclasses. , and have the functionality of all of those . superclasses. available to it.. This is called . Multiple Inheritance. .. It sounds simple, and it is simple, but it is considered a very tricky to implement in a clear way..  . Studying genetics . can be accomplished in part by . investigating the history of discoveries. that have lead to our . understanding of DNA and its role in gene expression and biological inheritance. 11.1 Basic Patterns of Human Inheritance. 11.2 Complex Patterns of Inheritance.
