Somebody doesn't understand basic genetics

By pharyngula on August 6, 2011.

Oh, boy. Look at these quotes from a recently published magazine article, and try to guess where they came from.

Scientists had also implicitly assumed that the X chromosomes in all women were identical.

We had? When?

The first comprehensive study of gene activity in the X chromosome of women reveals an unexpected level of variation among individual females. This extensive variation means there is not ONE human genome, but TWO - Male and Female.

This does not follow. There's also individual variation in chromosome 7, and every other chromosome in the genome. Allelic and expression variation do not make for calling every variant a different genome.

Chromosomes are the set of genetic instructions that guide the creation of an organism. Every human embryo begins with two X chromosomes, but in order to be a male, one of the X chromosomes turns into a Y chromosome.

Wait, how? Could this happen even now? Watch out ladies: if you watch too much football, one of your X chromosomes might turn into a Y.

Depending on the gene, having two active copies can matter very little or very much. When genes on the second X chromosome that escape inactivation are expressed, this can create a stronger overall concentration of particular genes.

That started out just fine, and then degenerated into gobbledygook.

Have you figured it out? You're probably thinking it's some wacky creationist journal, because they are always written by people who don't understand science and get the facts all wrong.

But no: it's from Health & Wellness magazine, written by Angela Hoover. The editor of the magazine.

The title of the magazine is a clue. What the heck is "wellness", and how is it different from "health"?
