More Than Just a Meme – How We Traced Our Maternal Lineage Using Our Mitochondria (Part 2)

Part 2 of our More Than Just a Meme series. Here, we get into the nitty gritty of how we sequenced our own mitochondrial DNA and determined our own haplogroups.


Gene Interactions

Genes can and do interact with one another (usually through biochemical pathways). These genes can be on the same chromosome or on different chromosomes. In this post, I will cover three important gene interactions and how they affect the 9:3:3:1.

Simple Pedigree Analysis

Pedigrees are diagrams that chronicle the phenotype/genotype of organisms over multiple generations. They can be used to determine the mode of inheritance of a particular disease as well as determine the probability of a future offspring inheriting it.

Do I or Do I Not Express B-Galactosidase?

The lac operon has been covered in another post along with the possible scenarios you could encounter. But what happens to B-galactosidase expression, permease expression and trans-acetylase expression if you have an extrachromosomal F’ factor episome that carries another lac operon? Well, not to fear! I will guide you through a sample problem giving you a systemic method to solve these types of problems.
