AI Thread Summary
The discussion revolves around analyzing a dog's genetic data, specifically a .TPED file containing 200,000 base pairs across 41 chromosomes. Users express interest in visualizing this data, with suggestions to create a karyotype for intuitive representation. There are recommendations to write code for aggregating the data into linear representations of chromosomes, including centromeres as wider blobs. Some participants note the potential to compare the dog's genome with known genetic maps to identify significant differences, such as deletions, and to predict features based on unique alleles. The conversation highlights the importance of understanding the relationship between a dog's breed, genetic makeup, and behavior, referencing existing research on the influence of genetics on canine behavior.

Well I just checked out my boy's breed of dog. Not what we expected...But the analysis came with some raw data, 200,000 base pairs on ... 41 chromosomes. They're in a .TPED file, which can be opened in Excel. Apparently, it an also be analyzed using PLINK software.

Wondering what I can do to visualize this data in a poster or something.

I mean, I could do it myself manually, but are there any existing options?

Have you considered making making a karyotype?

This will make far more sense to most people, kind of intuitive.
This is what karyorypes look like:

Assuming your data is presented as chromosome groups - DNA from one chromosome, then the next.

Write come code to aggregate the data into 41 linear blobs. Add a "centromere as a wider dummy blob" somewhere in the middle of each "chromosome".

Sort of free form art based on real data.

Sure.

I think my coding days are behind me.
 
There are probably already genetic maps and chromosomal pictures of dog genome available some where.
It might be interesting to know what are the major differences in your dog's genome vs. "normal", and then mapping them to the already known dog genome.
If lots of them map to a single location, maybe its something like a deletion (exciting!).

A list of predicted features your dog might have, based on its molecularly identified alleles that differ from "normal", would be interesting to compare with the dog's actual behaviors.
A big article on how much a dog or its breed influences its behavior and how that compares to the dog's genetic make-up: (https://www.physicsforums.com/threads/big-article-on-dog-breeds-in-science.1014733/).
They have looked at lots of behaviors and compared them with breed and genomic sequence.
That would probably be a good step on the way to a better genetic understanding of your dog.

Thread 'Did they discover another descendant of homo erectus?'
The study provides critical new insights into the African Humid Period, a time between 14,500 and 5,000 years ago when the Sahara desert was a green savanna, rich in water bodies that facilitated human habitation and the spread of pastoralism. Later aridification turned this region into the world's largest desert. Due to the extreme aridity of the region today, DNA preservation is poor, making this pioneering ancient DNA study all the more significant. Genomic analyses reveal that the...
