This lab was about nail patella syndrome which is a dominant trait on chromosome 9, where the individual has oddly-shaped finger and toenails, as well has peculiar kneecaps. This is part of a linkage trait because it’s on the same chromosome as the blood types and this can both cause what you have. In this … Continue reading Nail Patella Syndrome – Linkage

This lab was to help us learn how to take genes on a chromosome and to find the crossovers and where each is located on the chromosome. We were given the phenotypes of the parents and the children and we had to find the parent and recombinant classes. From there, we had to calculate the … Continue reading Great Gazooks – Linkage

This case study is about a woman named Josie who was experiencing very weird symptoms, wanting to drink blood, had photo-sensitivity, and seemed to be in a state of madness. She was diagnosed with Porphyria, which mimics symptoms of other disorders. This goes with complex traits, because more than one gene is affected to create … Continue reading Josie – Complex traits

This case study is about how epigenetics influence gene regulation, as epigentics are capable of turning genes off and on. This study is about a boy who had an aggressive cancer in the occipital lobe of his brain. People with this cancer had a lower survival rate depending on their genetics and how they would … Continue reading When a Gene turned Off Is a Matter of Life or Death

This was a case study about twin sisters, where one has schizophrenia while the other didn’t. This brought into question, how alike are twins? Identical twins are born with the same DNA, but over time, epigenetics cause modifications to the DNA, making the twins less identical genetically. In this case study, the twin who was … Continue reading Identical Twins, Identical Fates? Introduction to Epigenetics

This case study is about a pregnant wife who participated in what seems like a harmless medical genetic study, but turned into a bigger problem. She had her blood taken believing that she wasn’t a carrier for cystic fibrosis, but the result ended up with her being a carrier of the gene. She had her … Continue reading Sometimes it’s all in the Genes

This case study is about a mother who had her children diagnosed with muscular dystrophy. She had talked to a doctor and they had put the children in a medical study to try to find a cure for this disease. There were a series of phases and the children had gotten through phase 1 without … Continue reading Can a Genetic Disease be Cured? A Mother’s dilemma

We read a case study about a debate over genetically modified rice called Golden Rice. This rice was made to produce vitamin A because they are trying to find a food source that could provide nutrient for developing countries. This activity was where we could take sides on whether or not golden rice would be … Continue reading Golden Rice: An intimate debate case
