The daughter inherits her father’s X chromosome, which is the identical X chromosome that her father inherited from his mother. I know a lot of people are going to be disappointed because they don’t have the right mix of grandparents, or enough grandparents to test.
The only possible exception would be to confirm a specific Y DNA result matches a lineage as expected. I need to test, as does my living brother and the children of my deceased brother in order to recover as much as possible of my mother’s DNA. What really happens is that DNA is swapped between the two chromosomes in each pair before it is passed down. Here’s a quick peek at the first page of the Centimorgans section of the book. This can actually be very useful for genealogy, because several potential ancestors are immediately eliminated.
Your family members’ DNA is just as valuable to your research as your own. Living DNA: Known as the test that gives you the most British Isles-specific ethnicity reports, Living DNA is still working on its DNA matches experience. They may be ill, disinterested, or deceased, and you may not be able to upgrade their test at that time, so strike while the iron is hot.
The quick answer is that the odds are pretty close to 100% that you have DNA from your great, great, great grandparent. The Tech Interactive My father’s paternal side of his chart is entirely blank – because he only received his X chromosome from his mother. Fortunately, we have more than one kind of DNA to use for genealogy. It is important to realize that these numbers are just estimates and honestly, as long as the probability of your relationship isn’t zero, you are probably OK. The file you need to upload to Legacy Tree is not a raw autosomal data file like when you download your file to upload to GedMatch.
On the chart below, you can see how Natalie’s grandparents’ DNA maps across her chromosomes.

DNA Testing and Transfers – What’s Your Strategy?
Most people have 23 pairs of chromosomes for a total of 46.
The son inherits his entire X chromosome from his mother.
There is a good chance it is a little more or less than this because the DNA swapping in recombination is pretty random.
My policy is to test 4th cousins or closer. Of course our parents got their chromosomes from their parents. 442 Ancient Viking Skeletons Hold DNA Surprises – Does Your Y or Mitochondrial DNA Match? On average 50% though.
Mom ended up with half of one parent's DNA and half from the other (half green and half light blue). The odds of something like this happening would be very small...something like 1 in 8.4 million. There is a way to determine which ethnicity or ancestry regions you likely inherited from your grandparents, great-grandparents, and even great-great grandparents. DNA File Upload-Download and Transfer Instructions to and from DNA Testing Companies. You can increase your odds of having autosomal matches by making sure you are in all 4 major vendor databases.
You’ll notice that each parent carries more of each color DNA than they pass on to their own children, so different children receive different pieces of their parents’ DNA, and varying percentages of their grandparents’ DNA. (Again, you’ll learn more about these steps (and caveats) in Your DNA Guide—the Book.).
You’ll also be contributing to science by building the mitochondrial haplotree of womankind through the Million Mito Project.
If you know anything about how our DNA is passed on, this might seem weird at first. A grandparent DNA test from DNA Worldwide will determine the relationship of a child to its potential grandparents.
In you, these are randomly combined, so you can’t readily tell which piece comes from which parent. If they took a swab test, it’s MyHeritage or FamilyTreeDNA. As with the son, the daughter can receive an entire X chromosome from either her maternal grandmother or maternal grandfather. In this case, all of the spouses of Jane, Barbara and Harold are irrelevant to the grandmother and grandfather shown. As an example, I’ve included eye color, below. This nifty chart compiled by ISOGG shows the probability statistics produced by the major testing companies regarding cousin matching relationships.
For example, your first cousin has 12.5% of the genes you do (implying, inversely, that 87.5% of their genes are different).
The testing companies can’t tell you for sure, unless it’s a super-close relative like a parent or sibling. In fact, the two problems are similar. Our genealogist’s maternal grandfather can test for his (green star) Y DNA and (red heart) mitochondrial DNA.
You’ll find easy-to-follow step-by-step transfer instructions to and from the vendors in the article DNA File Upload-Download and Transfer Instructions to and from DNA Testing Companies.
Paired together, they form the two-sided shape we are familiar with. Instead it is slowly diluted away.
You may randomly inherit more DNA from one side of your family tree, than from the other. * The way you figure out these odds is you apply this formula: In this formula, x is the number of chromosome pairs that have to go a certain way (or the number of coin flips). great grandparent. For example, this is me compared to my father.
My book, Your DNA Guide—the Book, is the ultimate step-by-step, do-it-yourself guide to figuring out how you’re related to your DNA matches. If this is how things worked, then there could even be a small chance you wouldn't be related to your grandparents. from your great, great Anyone with at least one grandparent who has DNA tested from both sides can participate, meaning a total of 2 grandparents, but not through the same parent.
