PPT-1 THE CHROMOSOMAL BASIS OF INHERITANCE

The chromosomal basis of sex varies with the organism Sexlinked genes have unique patterns of inheritance Copyright 2002 Pearson Education Inc publishing as Benjamin Cummings Genetics 3 In human and other mammals there are two varieties of sex chromosomes . 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. Hypothesis: The antenna shape follows monohybrid inheritance, where the allele of Knobbed antenna is dominant and the allele for Short antenna is recessive. . Step 1: . Mate two individuals with short antenna. Contents:. Introduction to sex linked inheritance.. Chromosome carries which type of genes?. Three types of traits. Characteristics of sex linkage.. Types of sex linkage.. Sex linked disorders.. Sex linked inheritance :. Systems Programming. Inheritance. Introduction. Base Classes and Derived Classes.

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.. CS1 -- Inheritance and Polymorphism. 1. What Is Inheritance?. Provides a way to create a new class from an existing class. The new class is a specialized version of the existing class. CS1 -- Inheritance and Polymorphism.  . 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. 1. Chromosomal Theory of Inheritance. Theodor . Boveri. Walter Sutton. In 1902, Walter Sutton and Theodor . Boveri. developed the . Chromosome Theory of Inheritance. . . This theory basically states that Mendelian genes have a specific locus on the chromosome and that chromosomes undergo segregation and independent assortment during meiosis. . 12.1 Chromosomal Inheritance . 1. Genes are located on chromosomes; this is called the . chromosome theory of inheritance. .. 12.1 Chromosomal Inheritance. Chromosomes can be categorized as two types:. What if it’s NOT just the number?. Gene Mutations. Damaged Chromosomes . –. sometimes a portion of a gene or chromosome is lost or damaged during meiosis. Gene mutation. – a mutation that affects the gene. Prokaryotic cell. Plasmid (ring of DNA. ). 50 x Smaller 0.2-2μm. 50 x Bigger 10-100μm. And small rings of DNA called plasmids. Inside a nucleus. Main differences. Prokaryotes:. SIZE – 50 x smaller than eukaryotes.
