[TSwany]

We all know that Grey promises a part 2 to every video but is secretly allergic to making Part 2s

It’s crazy to me I’m related to so many people but I will never know most of them.

"You have parents."

I've seen enough. I'm satisfied

[DrRank]

There's one group you forgot about. If your parents become widowed or divorced and later remarry, their new spouse becomes your stepmother or stepfather. All the new stepparent's family relationships are the same as normal, but with the "step" prefix added. Any children they had from a previous relationship are your stepsiblings. However, if your stepparent and biological parent reproduce with each other, the new child is your half sibling, since you only share one biological parent.

Also, if you're adopted, you have adoptive parents, but this just means that you have two family trees.

6 years later and I'm still waiting for Family Genetics Grey!

"you have siblings"
*_laughs in only child_*

[dmOn]

@cgpgrey I don t know if anyone has already mention it, but after so many years I rewatched it, and my remark is that "in-law" is not a prefix but a suffix.
you are great. I ve been watching and promoting yu for more than I can remember.

Whenever I see a thing that requires knowledge of family trees, I always come back to this video, it's so quick and detailed, and I came here because I saw a meme saying "I am your Father's Brother's Nephew's Cousin's former roommate", and I now know that this dude is just your cousin's former roommate, although given the number of cousins that exists, doesn't really narrow much down, this dude could literally be your dad.

"when you get married"
Everyone in the spouse's family is sad

[SacsachCCABP]

The family tree should be in 3D - you can’t fit in the “in law” siblings unless you use a backwards line. But then that is more confusing, because you would have infinite layers of forwards/backwards lines since parents, grand and great, also have families and are only related through marriage.

"You have siblings and so do your parents"
Imagine having siblings
