There are other reasons to test for it on the regular. Like if you have an irregular cycle or your period is late. The number of times I used pregnancy tests when i wanted a negative result greatly out number the times I was checking for a positive result.

Funny you mention this I had to teach my husband how to read a COVID test the first time. I understood it immediately because of the pregnancy tests I took to make sure I wasn't pregnant prior to the pandemic.

Strong words from someone who clearly didn't click on the original link and watch a 5 minute video.

Science requires one to cast aside ones prejudices and have an open mind to come to new understanding. Identical twins have more than just DNA in common. Look up some studies on identical twins if you are interested.

This does kind of get to the point of the exhibit. The researcher gave the press of the higher percentages to the press to give a more "potentially accurate" model. However most of the sculptures were created to showcase all the possibilities. Meaning there was a small chance that Chelsea could have looked like some of those but it was still there.

Skin tone is an interesting one, we would think it is simple but it is not. To use myself as an example my skin tone shade is closer to my mother's: light than my father's: medium-dark. However the undertone of my skin tone matches my father's golden undertones versus my mother's pink undertones. Which means the more of a tan I have the more I look like my dad to people. I also have my mother's eye shape but my father's eye color. My mother's hair color but my father's hair texture pattern.

I could go on but the point is that genes can really express themselves in a lot of varying ways.

I believe the more information you have the more accurate you can probably get. I realize my response could read as a skeptical one. I just find this stuff very interesting and my personal thoughts on this are kind of a side tangent so I didn't include them in that post. I did in another response in this thread though if you are interested.

In the case of Chelsea there was no skull because well, she's still alive.

I think the more information you have the more accurate you can get. In the case of Chelsea there only was DNA available. Personally I find this stuff to just be very interesting. While some people are skeptical I just find this to be an intersection of art and science. In the Probably Chelsea exhibit they explain that the ones picked to show the media were of the higher percentages. However since Chelsea was open to it there was more they could depict based of her DNA. It's a pretty powerful exhibit to see because some of the possibilities look nothing like Chelsea. A person with that face would be identified as a completely different race as Chelsea. To me it empathized how much the concept of race is really a social response to the expression of a person's DNA. The idea that we could look like basically anybody else is really powerful.

It's a side tangent but if you are In San Francisco I recommend checking out the Exploratorium. It's a really fun and thought provoking science museum.

There is an exhibit called Probably Chelsea at the Exploratorium in San Francisco. It depicts several different sculptures based off the same DNA of a person. There is a lot of room for interpretation of things like DNA it seems.
