Unlikely. It’s not like if I didn’t get my sister’s specific danish gene

She got from our dad, that I’m going to get a Japanese gene. I’m probably going to get a different danish gene or some other gene from the same pool of genes we are both pulling from. So siblings are more likely to be relatively close since they pull from the same pools.

How do 2 siblings (same 2 parents) get slightly different DNA/ancestry results?

UPS?

Not UPS, USPS, Fed Ex, And DHL wasn’t even around back then

Kids don’t actually get identical genetic packages from their parents.

Right. But how can this be

Because your mix of DNA is unique to you

Your kids got half your DNA and half your wife's. That means you each have

...brother from the father's brother?

Because DNA comes in packets - not all packets are the same.

A few years ago there were identical triplets that all got significantly

No, DNA doesn’t work that way. For example

Care to share? Sounds interesting. The discovery part I mean

My grandpa’s brother fathered a child we found this way. At the age of 68 my dad got a new cousin out of nowhere.

Crazy story about this with my neighbors

My MIL found her siblings through Ancestry

Siblings don’t inherit the same 50% of DNA from each parent.

Let's say each parent has 100 genes. Each kid gets 50 genes from each parent

Thanks. That’s the best explanation I’ve heard

byu1

This is right. You only share 50% of your variable genetic material in common with any sibling.

mvtoro

7/16/20 12:06am

*on average. You can share more or less depending on which chromosomes you inherited.

Sure. But for the purposes of this question it doesn't really matter if it's 50, 49, 51... It's about the fact that only

Your example presupposes a high percentage of Danish genes overall in the genes of both parents. The likelihood of

My point is that you're not going to get something

Chasicle

For percentage of geographical distribution of genes, you're right. It won't look like you're 50% "different" in terms

So why the big fuss over incest? 🙂

The replies above are right, but they don't really address the primary

Every person has two sets of chromosomes, each set with 23 chromosomes. One set is inherited from mom, one set from dad.
