What is a Half Sibling? // DNA EXPLAINED

What is a half sibling? You may have come across someone that is claiming to be your half sibling and you want to know how you two are related. In this video, I show explain to you how a half sibling is related to you, and what DNA you may share with one another. With each situation there are exceptions which I have explained below.

• CENTIMORGANS •

The Average Half Sibling shares between 1339cm and 2232cm, which is equivalent to between 18% and 30%, with the average being around 25% (1860cm).

• There are exceptions and DNA anomalies which makes is possible to share between 14.2% (1056cm) and 35% (2604cm), though the chances are usually a lot smaller.

►According to the website DNA Painter, the chance of being a half sibling at a 14.2% DNA share is a 0.08% Chance.
►The chance of being a half sibling at a 35% DNA share is a 0.07% chance.

The Term 'cm' stands for Centimorgans*

I knew someone who married their half brothers half sister. Their half brother was related to his wife, but he and his wife were not blood relatives, but both of them were half siblings to their brother, sounds wrong but isn't actually incest.

So is it half if you have the same Mom and your dads are brothers meaning your Brother/ cousins? Can you make a video on that

How much are half siblings kids related

[k_krabco]

So it's like this,
If my step mom have a kid, from her old husband, it's step sibling.
If MY dad and my stepmom have a kid, it's my half sibling?
Is that what half sibling means? Sorry I'm not a native English speaker so I don't understand well

Hello, what means Combined Siblingship Index of 3.9315? Is there a maximum Combined Siblingship Index to make comparison to results? Thx

Half siblings with same mother but have different fathers never get along the way that siblings with same father and mother do

I know from personal experience my half brother has different father than I do and we don’t get along at all if we had the same father we would why along.
