Mendelian Genetics Introduction Gregor Mendel experimented with pea plants for seven years in a small garden in a monastary near Brno, Czechoslovakia in the Austrian Alps. During those seven years he worked with plants that had certain traits that came and went in predictable ways. In many cases he noted tall or short plants but no medium size plants, for example. When he crossbred a tall plant with a short one, he always got a tall plant. But those "tall" seeds from these plants produced a few short plants in the next generation. The experiments led to dramatic insights into how genetics worked. This module will help you understand some of the basic principles that we believe govern the blueprints for life. Mendel worked with traits such as color, stem length, and nature of the seed. As he performed his experiments, he recognized "weaker" traits and "stronger" ones. He named the stong traits DOMINANT and the weaker one RECESSIVE . In order to conceptualize this relationship, explore this brief explanation of what Mendel did. First Generation: Mendel began by producing a series of true-breeding pea plants. This meant that he was sure he had only traits for yellow or green when he began to crossbreed plants. In the first cross, Mendel saw only the "strong" trait for green color. There was no direct evidence that the yellow trait existed.

Biology 130 Lecture Notes: March 13, 2002 Mendelian Genetics and Beyond Class Business: Exam are graded and ready to be picked up in my teaching lab (Rm 204). Reading Assignment: Read all of Chapter 14, pp. 239-260) and see tutorial links given at end of page Review of Last Lecture: In the last lecture I discussed the basics of Mendelian inheritance. Mendel provided quantitative evidence for the particulate theory of inheritance and formulated two rules of inheritance: Law of Segregation: Each parent possesses two copies of a gene and these segregate into separate gametes. Law of Independent Assortment: Genes segregate independently from each other (evidence from dihybrid cross). In today's lecture I will discuss several deviations form Mendelian patterns of inheritance. I. Beyond Mendelian Genetics Incomplete Dominance: F hybrids have intermediate phenotypic appearance. Example: Red snapdragons crossed with white snapdragons produce pink offspring ( Fig. 14.9 2. Incomplete dominance does not support blending hypothesis of inheritance. Codominance: Both alleles are manifested in phenotype.

Review of Last Lecture: In the last lecture I finished lecturing on Mendelian genetics and deviations from clear cut dominance relationships including incomplete dominance and codominance. I also discussed the phenomena of epistasis pleiotropy , and polygenic inheritance . I discussed the effect of environment on phenotype: Phenotype = Genotype + Environment and human genetic diseases. I. Relating Mendelism to Chromosomes 1. Chromosomal theory of inheritance formulated around 1902. suggests that Mendelian genes have specific loci on chromosomes and that chromosomes undergo segregation and independent assortment (Remember Mendel's two laws; Fig. 15.1 2. Morgan using fruit flies ( Drosophila melanogaster) to study inherited traits. identified mutant fly with white eyes (normal color is red = wildtype; Fig. 15.2 3. Morgan discovered sex-linkage. Crossed white eyed males with red eyed females. Crossed red eyed F generation: Only male flies in F generation had white eyes Eye color gene is on X chromosome: Females carry two X chromosomes while males carry only one X ( Fig. 15.3

Math 338, Spring '03, Lecture 1 Outline The mathematical and modelling techniques we introduce in this course will be applied mostly to problems of genetics and biological sequence analysis. We start with a very brief sketch of some fundamental concepts and definitions of genetics, the science of heredity. For illustrations and further explanations, this page provides links to the web site , associated with the text, Biology by J. Kimball. Genes and DNA Prior to the amazing advances of molecular biology in the second half of the twentieth century, heredity was understood in terms of Mendelian genetics. Mendelian genetics postulates that traits are passed down from generation to generation in discrete units called genes . In Mendel's pea experiment, peas grown from various crosses turned out either wrinkled yellow, wrinkled green, smooth yellow, or smooth green, and these traits were handed down independently from generation to generation. We describe this situation by saying that there are two genes for pea color, green and yellow, and two genes for skin type, smooth and wrinkled. The alternate genes governing one trait or characteristic are called alleles of one another; thus the gene for yellow peas and the gene for green peas are alleles for the trait of color.

E.g. both A and B alleles are expressed in human blood type AB B. Multiple Alleles - may be more than two alleles for one locus, but each individual inherits only two alleles 1. E.g. ABO system of human blood type involves three alleles 2. As a result, there are four possible phenotypes or blood types: A, B, AB, and O C.

Mendelian Genetics Mendel's first hypothesis was that " Alternative versions of genes account for variations in inherited characters. " What he was talking about were alleles, or different versions of genes that affect the same characteristic. His second hypothesis was that, " For each character, an organism inherits two genes, one from each parent ". This was refers to the fact that when somatic cells are produced from two gametes, one comes from each parent. The alleles are either the same, or they are different. His third hypothesis, stems directly from the second, " If the two alleles differ, then one, the dominant allele, is fully expressed in the organism's appearance; the other, the recessive allele, has no noticeable effect on the organism's appearance. " Finally his fourth hypothesis is that " The two genes for each character segregate during gamete production, " which refers to the fact that each reproductive cell has only one of each pair of alleles, which will meet up with its pair when the reproductive opposites meet up and create a new organism. Mendel's work was with peas, and most schoolchildren learn a little of Mendel's theories in school. However we will go into much greater depth, and apply this information specifically to mice.

Mendelian Genetics In this lecture we will discuss the basic principles of the transmission of genes from parents to offspring by examining Mendel’s work. Before we begin, it is necessary to clarify the concepts of genotype and phenotype. The genetic constitution of an organism is the genotype. The phenotype is an observable characteristic or set of characteristics of an organism that result from the interaction between its genotype and the environment. Mendel Experiments Mendel was an Augustinian monk who in 1854 began a series of breeding experiments with the garden pea to explain the transmission of hereditary characters from generation to generation. The basic approach was to mate two individuals that differ in phenotype, and to analyze the phenotype in the resulting offspring. Mendel obtained 34 strains of pea plants that differed in a number of characteristics. Then he allowed self-fertilization for many generations in each of the strains to make sure that the characteristics he was studying were inherited, and that they remained unchanged for parent to offspring for many generations. These strains are called pure-breeding strains.

Extension of Mendelian Genetics Analysis Multiple alleles Not all genes have only two forms; many have multiple alleles. No matter how many alleles there are in a population, a diploid individual will have only two alleles, one in each homologous chromosome. We already talk about the ABO blood groups, but let’s bring back that example to illustrate systems with multiple alleles. ABO blood groups result from a series of three alleles ( I A , I B , and i ) that combine to produce four phenotypes (A, B, AB, and O). Both I A and I B are dominant to I , while I A and I B are co-dominant to each other. People with genotype I A I A or I A i are blood type A, people with genotype I B /I B or I B i are blood type B, people with genotype I A /I B are blood type AB and people with genotype i/i are blood type O. ABO inheritance follows Mendelian principles. Another example is the gene for eye color in Drosophila , where here are about 100 alleles for the locus. Morgan (the same guy who worked on segregation of the eye color locus in Drosophila ), experimentally crossed a white-eyed female with a vermilion-eyed (
