We were learning about chromosome mapping with this lab. We had to throw a stick across a line and marker how many times a gene had a crossover; we did that a hundred times. Then we had to calculate the frequency of each by taking the number of times that gene had a cross over, … Continue reading Chromosome Mapping – Linkage

Nail Patella Syndrome – Linkage
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
Great Gazooks – 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
Complex Traits Blog
There are monogenic and complex traits within us. People are mostly taught how traits have two alleles and can be influenced with those genes. They provide a classic pattern with dominant and recessive. This is classified as monogenic traits. Yet, there are the traits that are influenced by several genes causing different variations, not following … Continue reading Complex Traits Blog
Josie – Complex traits
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
