Epigenetics
Identical Twins, Identical Fate? Epigenetics is the study of the chemical reactions that activate and deactivate parts of the genome at strategic times/locations, and the factors that influence them. According to the article within the case study, during an identical twin’s lifetime, epigenetic changes occur to their DNA that can affect gene expression. Therefore, one … Continue reading Epigenetics
Personal Genetics
Four Corners Activity The Four Corners Activity was an activity done on the first day of class to help us form opinions and make personal decisions involving genetic diseases. We were asked to agree or disagree with questions involving people’s personal genetic situations. This activity was a clear example of Learning Goal #6: Personal Genetics. … Continue reading Personal Genetics
Gender Linked Traits
Gender and Genes – How They Interact For most inherited traits, the gender of the bearer of the genes is unimportant. However, there are exceptions that fall into three categories: sex-linked traits, sex-influenced traits, and sex-limited traits. Each one of them have different characteristics that make them unique: A sex-linked trait is a gene found … Continue reading Gender Linked Traits
Mendellian Genetics
Characteristics of Autosomal Recessive/Dominant Traits When it comes to dominant genes on an autosome (any chromosome other than a sex chromosome), the alleles and their associated traits are either autosomal dominant or autosomal recessive. They are both examples of ways that a trait or disorder can be passed down (inherited) through families. A mutation in … Continue reading Mendellian Genetics
Modes of Inheritance
Dragon Genetics Lab In the Dragon Genetics Lab, we studied the patterns of inheritance of genes in dragons, which had two pairs of homologous chromosomes in each cell. In this lab we see that the patterns of inheritance are determined by the behavior of chromosomes during meiosis and fertilization, which is why this activity is … Continue reading Modes of Inheritance
Final Research Essay
For this essay, we researched three questions that we had brought with us into the Genetic Diseases course on day #1. Now that we have experienced the whole course, we may be able to understand the answer to our questions better than if we had researched them a month ago. I chose questions that I … Continue reading Final Research Essay
