BIO 150 1nd Edition Lecture 23 Outline of Last Lecture I. Genetics of CardiomyopathyOutline of Current Lecture II. Genetics of Cardiomyopathy III. Crossing overCurrent Lecture- Crossing over occurs more between genes that are far apart- Distance affects recombination rates- Genes that are close together are unlikely to cross overRecombination:Uses 1. Map gene order on a chromosome 2. Distances on the chromosome-We study crossing over in order to observe the recessive phenotypes (homozygous)-Parental phenotypes are all the same in reference to color meaning that they are observed as the more prominent -When recombination occurs, the phenotypes of the genes will be crossed – meaning they will contain two colors-There are many alleles present in the same gene-Different diseases may contain different types of alleles-These alleles could be newly found and not yet diagnosed-Therefore if a disease is caused by an allele that is not yet been discovered, one should These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.1. Run tests on the family members who are also diagnosed with the same disease and see their allele that is malfunctioning2. Run tests on family members who are not diagnosed with the disease3. Cross examine the tests and find variation between the two different allelesTraits are controlled by:1. Genes2. Environment “different climate, exercise, diet, stress, exposure to chemicals that are
