Looking for a half brother I apparently have

Hello everyone.

I'm looking for a half brother who I may have living or born in florida. (From what I was told)

He would be around my age 36, around 1990, and either know his father's name that abandoned him or have no father on his birth certificate.

His mother went to my mom to ask for help and was turned away.

My father has lived in Kansas, New York, and PA. Is a vet, used to be a truck driver.

It's kind of a last effort but I thought why not.

Is it possible for twins to have different womb dna’s? For example swapped?

I mean there are studies about parents having low percentage of DNA on their kids and it cause so much trouble(doubts of infidelit) and some studies found the mother’s womb or the father’s reproductive organ produces their unborn twin/sibling‘s dna on cells(semen or egg they release) much more than their own… is it possible for twins to have their reproductive cells swapped? I mean… are there cases like this?

Genetic mark to find relatives.

I have created this account specifically hoping to find any long lost or distant relatives, purely out of curiosity.

In my family we share a genetic mark, much like a birth mark, but the exact same mark, in the exact same location. It has appeared in both Men and Women, my Grandad and my Aunt both have it, but none of my cousin's or my siblings.

I don't know how far back this mark goes i.e when it first occurred, so the possibilities are endless.

The mark is like a faint bruise in colour, purple and red, shaped roughly like Australia, on the base of the spine, just above the coccyx.

Anyone who has this exact mark should be a relative, however distant.

Did a DNA test change how you live or parent? Journalist looking to chat.

Hey everyone! I’m a journalist at The New York Times working on a story about DNA testing and screening, and how it impacts our lives, choices, and parenting. (My body of work is linked below.)

Whether you used a consumer kit like 23andMe or went on to upload raw data to a third-party app like GenePlaza, I’d love to hear your perspective.

I’m especially interested in chatting with:

  • Anyone who has tested themselves or their children for medical, behavioral, or cosmetic traits.
  • Parents (or future parents) who are using these genetic insights to guide parenting, lifestyle, or healthcare decisions.
  • People who haven't gone through with a test or screening yet, but are actively planning to.
  • Anyone else with an unexpected DNA testing experience that you would like to share.

I want to understand individual experiences: What is motivating you to pursue this? Did your results actually change your decisions or plans? Did they give you peace of mind, or introduce more questions and ethical dilemmas? If you're still considering a test for a child, do you and a partner have differing opinions?

If you're open to a brief chat about your experience, please drop a comment below or send me a DM. You can also email me (if you want to independently verify my identity) at emily.baumgaertner.nunn@nytimes.com. Thanks so much!

Lab/Court messed my paternity test up 36 years ago.

So, during the 90s my parents got a divorce. My mom married my father already pregnant but his lawyer recommended getting a paternity test because he signed the birth certificate. Long story short, the results said somehow he was my fatner. It stunned everyone because he had a vasectomy years prior. I know nothing is 100% but I’ve now taken two seperate ones as a adult and it show I have no biological relation to him or any of his family,but I do have relatives all over the place with the last name of the other man in question. The father I knew growing up rarely had anything to with me because he struggled with addiction issues, but he also never missed a child support payment either. He’s now passed, but my siblings on his side haven’t and I feel a duty to him and them to tell them the truth. I also recognize I could have been lied to about the original test, but I’m pretty confident in the two I had done in 2025-26. My moms 78 and has dementia so I can’t get any real answers out of her and I just don’t know what to do. I know the other man but I don’t want to hurt them either because he was married to another woman when my mother conceived me. What do I do? I don’t want to hurt anyone but I deserve to know this.

Buproprion and DNA test

Hi, I’ve been on Buproprion 150 mg for 9 weeks and I feel worse (anxiety/depression)
Also on Effexor (Venlafaxine) , 150 mg for 15 years. It worked great until 2 years ago when I experienced burn out.
Just got a DNA test back which showed that Buproprion might not be the best fit for me.
Has anyone had a DNA test done and switched medication because of it?

My niece and I share enough dna that 23andme connect us as sisters. Is that strange? How does that happen?

My niece and I share enough dna that 23andme connect us as sisters. Is that strange? How does that happen? It makes me wonder how many relatives maybe haven’t connected because the dna amount?? My true sister obviously showed up as my sister but my dad and I shared a few more % then my sister and him. I just find it interesting and when it popped up that we were sisters not aunt and niece was odd!

Learning about genetics in 3 different levels - Community feedback

I got into genetics a few years ago and I decided to build a free interactive site that explains all topics in 3 different levels (explain it like i'm...). I think it provides a nice learning path and lowers the threshold without taking away the option to get into more scientific explanations. A core component is the ability for users to provide feedback to ensure scientific accuracy. It would be cool if you could check it out and provide feedback where needed or learn a thing or two!

Ancestry DNA kit showed my dad wasn't my dad

9 years ago I was big into building my family tree. I bought an Ancestry DNA kit. While I waited for the results I got to build a family tree using their site.

Back story. My mom was married to John but left him for my dad Ed. She was married to Ed until I was 2. He got visitation every other weekend but I very rarely saw him and instead stayed with his mother who spoiled me. So basically I didn't have a present father figure.

Once the DNA kit was complete I was shocked to find that no one on my dad's side matched my DNA, but my DNA matched several people with the same last name as John.

I sat with this for weeks. I called my mom but unfortunately she had had several strokes and had dementia. She acted like she told me years ago. I think I would have remembered this. I had a lunch date with my stepmom (Ed's wife) and told her. I know the news would come better from her than me. We were very low contact. Then I found John's number. He lives an hour away and owns a mechanic business. He was surprised by the news. After a few weeks he called me back and wanted to set up a lunch date. I look a lot like him.

When we had lunch I told him I was 38 years old and didn't expect anything from him but I would like family medical history for myself and my biological kids. He told me he wanted to be a part of my life and get to know me. I told him I would like that but I wanted him to know that I was married to a black man (I'm white), my biological kids are biracial, my adopted daughter was black and my teen son was gay. I told him if he had an issues with this we could part ways.​ He says that's no problem, he loves everybody.

Things were great for three years. I have two half sisters and a half brother. We had cook outs, holidays, they came to my kids school events. It was nice.

Fast forward to 2020. September I discovered my husband was having an affair and I ended my 20 year marriage. October my 18 yr old had intended to end her life. She was admitted for a hospital to help her. (O that August I had got custody of my adopted daughter's sister. So I have a newborn that is going through withdrawals) Things were extremely stressful for me.

November 2020 John calls me and says he tried to get past the fact I married a black man. He says maybe if I had raised you it would be different. He says you and your kids need to stay in your city and we will stay in our city. I told him I appreciated the honesty but he could have told me this 3 years ago. I say if I could live my life over I would choose my children everytime.

That was my last contact with him, his wife or my biological siblings.

I regret letting him in my kids lives because they were calling him pops within that three years.

Is RX Enough? ACTN3 Question

My question is simple: is the RX configuration of the ACTN3 polymorphism enough to get the majority of the strength benefits, even if RX individuals have 50% of the alpha-actinin-3 protein expression of RR individuals?

In olympic powerlifters, the RR and RX ACTN3 configurations seem to be commonly prevalent. On the contrary, the XX genotype is completely absent. It seems that on the elite level, having ACTN3 XX can limit you from competing in strength competitions. If RX is so common in elite powerlifting, how much better is it to have RR instead of RX?

Genetic testing without matching with relatives?

If you do genetic testing, is it possible to make sure that you are not linked with biological relatives, and they have no way of being linked with you? Is it possible to only look at an ethnicity breakdown, and no genealogy?
