You inherit different parts of your history, and not equal parts. Siblings don't look exactly alike for this reason. |

My mom and dad both tested (I haven't yet - but assume I can just rely on their data).
Mom was 100% UK. Dad was 99% Uk and 1% Ashkenazi jew from the north of Spain. That was kind of funny - like, the most white, waspy, could-have-been-on-the-mayflower make up. Except 150 years ago, someone in Southampton probably had a wild weekend with a Jewish visitor from Spain. |

Incorrect. They originated from northern India, long ago. I grew up in southern Scotland and my father’s family is Romany. Some still travel by horse drawn caravan and will stake out their horses to graze near my sister’s home. |

My dad found out his sister is only a half sister.
My cousins are mostly European and a little Indigenous, but also had Egyptian, Arab, and Mongolian. |

Ethnicity is not inherited in equal parts, so you don’t get 50% of DNA from each parent. |

This doesn’t add up. Biological siblings should be fairly similar. There is variation but not like what you are describing. If your mother is 100% Italian, you both should be about 50% Italian. If your sister is 60% that means she inherited 10% Italian from your father’s side as well. The fact that you’re only 20% doesn’t make sense. As for your son having 35% Italian (more than you!), that indicates his father had some Italian DNA as well. |

Half of your DNA is from your mother and half is from your father. Each side is recombined so you get a random mixture from each parent. If your mom is 100% Irish and your dad is 50% Italian and 50% ashkenazi Jewish, then half of your DNA will be Irish, and half will be a recombination of Italian and Jewish. On that side, it may be an equal 25% Jewish and 25% Italian. Or, it maybe 40% Italian and 10% Jewish. THAT is how siblings get different results. But each sibling would be approximately 50% Irish. |

I think it's because humans have been mating with each other across culture for 100,000 years, so it's actually hard to pin down what an "Italian" is. For example -- I took the test. I'm Indian (Bengali) and both my parents are from the same region of Bengal, as are their ancestors for as long as anyone can remember -- like, hundreds of years and many generations. I look like a completely typical Bengali woman. But when I took the test, my results were 50% South Asian, 25% Central Asian, 25 % Southeast Asian. The only way this makes sense is because people in this region have been migrating and mating over the last, like 10,000 years. I read into their methodology and they said they take a "typical" person from that region and compare you DNA to that person. I *am* a typical Bengali person, but that's the breakdown I got. |

| No real surprises in my family but DH found out about a lot of secrets in his family - the unknown cousin who is a child of his uncle that has never been discussed, as well as his parent's sibling only being a half sibling due to an affair and the newly discovered parent of that half sibling being someone well known to the family who lived close by. |
