What explains sharing a 28.6 cM DNA segment with a sixth cousin?

How many cM of DNA do cousins share?

Note that a given relationship, such as first cousins, can share varying amounts of DNA because of recombination (“shuffling” that occurs at conception). You usually share about 850 cM with a first cousin, but that number could be as low as 553 or as high as 1,225 cM.

How many centimorgans do 7th cousins share?

7th cousins can share as little as no DNA with each other, and as much as 50 centimorgans (about . 67%). In other words, seventh cousins share between 0-. 67% DNA.

What does 22 cM mean in DNA?

You will also see that figure expressed in centimorgans. Centimorgans (cM) are units of genetic linkage between two given individuals. For example, if you share 1800 cM with an individual, that means you share around 25% of your DNA with them. A strong match will have around 200 cM or more.

What does 30% shared DNA mean?

High. 30—45. About 95% You and your match share enough DNA that it is likely you’re both descendants of the same common ancestor or couple, but there’s a small chance the common ancestor(s) are quite distant and difficult to identify. Good.

What does cM shared mean on ancestry?

A centimorgan (abbreviated as “cM”) describes the length of a piece of DNA. It is a unit of measurement. More specifically, it measures the distance between two chromosome positions. A shared DNA segment is a chunk of genetic material shared between two individuals. The length of a segment is reported in centimorgans.

What is considered close family on AncestryDNA?

Your AncestryDNA close family matches could include an aunt or an uncle, a niece or a nephew, a great-grandparent or a great-grandchild, a half-sibling, or a double-first cousin. Someone who appears in this category is rarely a first cousin.
