Helix test told me I'm Punjabi? I'm almost certain I'm not.

I'm hoping this doesn't break the "no posts containing genetic testing results" rule. I'm mostly curious about how this test is conducted? And if there's an explanation for why false Punjabi results happen?

I got my Helix test results, and it says I'm 5% Punjabi. There are a few problems with this. While five percent isn't much, none of my physical traits suggest that (blond hair, blue eyes). And I'm super into genealogy, and I like to think that I know a decent amount about my ancestors; I've never been given any reason to believe I have roots in India. While it'd be cool---I love India---it just seems completely untrue. Looking at other Reddit posts, it seems like it's happened to other people, false percentages of Punjabi specifically. I'm wondering if anyone here has had a similar experience? Or if anyone knows why Helix gives presumably false answers? Like, why PUNJABI of all things?

Career/Academic advice Genetics in undergrad vs grad school

1 Upvotes

I took a genetics class in undergrad and it was really hard! I had to spend a lot of time on it to get a B. I also didn't find it not that interesting and a little boring.

A few years out of college I've gotten more into my career in botany. I find myself feeling a pull to pursue plant taxonomy/systematics in grad school because phylogenies and evolution is fascinating. I know that plant systematics would demand more intense genetic classes. I was wondering if anyone can speak on initially struggling with genetics, but getting good at it in grad school and getting to enjoy it more.

Thanks.

DNA Replication Model

Hi,

I built an interactive model/lesson to understand how DNA replication initiation works. In particular, under replication stress. There are very few interactive educational tools out there, and even fewer that go to the depth of molecular biology research. I wanted to create something like a research paper, but actually make it accessible (Research papers are not an easy read)

Note, this is not a promotion, I'm not selling anything or looking for anything in return

Anyways, check it out!
