Borland Genetics

At Borland Genetics, we offer a suite of cutting-edge tools designed to take your genetic genealogy research to the next level. Whether you're reconstructing ancestor DNA or visually exploring chromosome inheritance, our tools give you the power to dive deep into your DNA connections. Here's a look at our most powerful chromosome mapping features: 1. HIR Mapper The HIR Mapper is a dynamic tool that generates chromosome maps by identifying segments of DNA shared between your focus donor and matches in the Borland Genetics database. The resulting phase map visualizes recombination points from the most recent generation of inheritance, helping you track which segments came from which parent. Key Features : Incorporates matches from Borland Genetics and GEDmatch Segment Search. Displays DNA matches, grouped by segment or block, with options to review and adjust. Outputs phase maps to help visualize inherited DNA and recombination points. Perfect for users mapping DNA inherited fr...

  It occurred to me today that I have not yet done a tutorial on how to use the Borland Genetics “Segment Lab” tool.   Introduced as part of last October’s anniversary “Fall Features Release,” it’s one of the newest tools on the site, and probably also one of the most under-utilized.   Hopefully, this demonstration will show how it’s also one of the most valuable tools on the site. The Segment Lab is Borland Genetics’ native chromosome map/phase map editor.   While a far cry from a robust chromosome mapping solution like DNAPainter, it has specialized features that I designed to make our task of ancestor DNA reconstruction easier, and to help maximize the reconstruction coverage of our output ancestor kits. Before we dive into using the tool, I want to point out that the Segment Lab is NOT a tool that creates a phase map from scratch.   At Borland Genetics, that’s what the HIR Mapper does, and when it comes to mapping matches from outside the Borland Genetic...

What's the Difference Between Build 36 and Build 37, and Should I Care? To even begin to tackle this problem, we’re going to first need to understand what a “build” is.   Perhaps you may have seen references to “build 36” or “build 37” on FTDNA or GEDmatch or Borland Genetics, or to “build 38” on SNPedia.   Never heard of SNPedia?   We’ll cover that in future editions in this blog.   But to get to the point, when you hear these terms, we are referring to sequential versions of the accepted map of the human genome by the scientific community (or a dedicated group of scientists thereof known as the Genome Reference Consortium).   Each build represents a refined understanding of the sequence of base pairs along our chromosomes. A loose analogy to build versions would be the sequential editions of the Rand McNally road atlas, but with one major difference.   When Rand McNally publishes subsequent editions of its atlas, it generally does so becaus...
