BS 162 1st EditionLecture 9Autosomal Dominant Trait- Only need 1 copy of the gene to show the trait (i.e. trait is dominant)- 50% chance that it is passed on to offspring of a person that has the abnormal copy- if you do not show the trait, there is no chance of passing it onto the offspringExamples of Autosomal Dominant Trait- Huntington’s Disease- Huntington’s disease causes neuron death in 3 parts of the brain which leads to uncontrolled movements, emotional disturbances, and mental deterioration- Abnormality in 1 geneAutosomal Recessive- Both parents pass on the allele for the condition…only then will it be expressed- Individuals with one copy of the allele have a normal phenotype, but they are “carriers”Sex-linked- on either X or Y chromosomes- Hemophilia: the protein that helps your blood clot is not produced correctly. In 5,000 males have hemophilia. This gene is found on the X chromosome.How does human genetic information move from generation to generation? Pedigree Analysis- in humans, pedigree analysis is an important tool for studying inherited diseasesThese 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.- pedigree analysis uses family trees and information about affected individualsInheritence, how info is passed on and how it is expressed- typical mendelian genetic inheritance patterns- non-mendelian genetic inheritance patterns- gene therapy- epigenetics- GMOsGMOS- a certain gene (or even a promoter, regulator) from another species is added to an organism to achieve some desirable quality in the GMO food or
