Autosomal testing vs Mitochondrial testing (mtDNA) vs Y-Chromosome testing

Genealogy, science
When going over your options for a direct-to-consumer DNA test, the options can be overwhelming. Between the different companies available, testing methods used, and services provided, it can be hard to choose a company and plan with any confidence. In terms of testing methods alone, there are several approaches different companies take to analyze your genetics. In general, companies tend to analyze up to 3 different parts of your genetic code. The majority of companies test your Autosomal Chromosomes. These chromosomes represent a majority of your DNA. They account for 22 of the 23 chromosomes. The 23 chromosome is your Sex Chromosome, and contains two forms: X and Y. Females have a pair of X chromosomes, while men have an X and a Y. Because the Y is always passed down…

Genetics Terms: Things to Know about DNA Test Results

science
Before you order a DNA Test or whole-genome analysis, you should probably beef up on some of those biology terms you have long forgotten. But worry not! This guide will lead you through all the terms you need to understand when getting the results from a direct-to-consumer genetic home test. First Things First, What is DNA?  DNA is shorthand for deoxyribonucleic acid. This molecule holds all of the information your cells need to survive and reproduce. DNA is stored as chromosomes, and humans have 23 unique chromosomes. Each of these chromosomes contains the information necessary to produce various proteins, which work together in immensely complex networks to form a functioning body. On each chromosome, there are multiple genes. Each gene is made of small molecules called nucleotides. There are only…

Criticism about Home Genetic Testing

As much as direct-to-customer home DNA kits have been sparking interest across the globe, there has been rising criticism about them. The criticism is normally not geared at one individual company (while 23andMe are taking most the heat being the biggest and running into trouble with the FDA in the past) but rather about the concept of offering DNA kits to people and supply information which is either not accurate enough or cannot be used clinically. Everyone loved 23andMe and other home genetic test kits as long as they focused on novelty; when marketing started focusing on personal DNA kits as a diagnostic tool, that's when all hell broke loose.
