1 attached, 1 unattached earlobe

Postby thermal » Mon Dec 10, 2007 5:46 am

Hi,

I have one attached and one unattached earlobe. I always was a little bit proud of it because I have never heard of anyone with this feature. A long time ago a friend said he told his geneticist friend about it and she didn't believe him saying it was impossible.

I never bothered investigating it but recently my interest has been piked.

What does it mean? Am I some future evolution of human and likely to develop super powers momentarily?

If anyone doesn't believe me or wants to see I can provide photos.

Dude, I do too. One attached one unattached. We did this thing in like 6th grade with genetic traits and she said I must of had something happen to it. But whatever! I totally wanna high five you.

normally, they are the same trait, determined by the same gene. that is why the genetics enthusiast said it was impossible. But your condition is surely not the cause of genetics, but of some anomaly in development. No idea what though...

It can be a mosaicism, where during development you don't get proper distribution of chromosomes - cells that developed one ear were missing the chromosome that had the dominant allele, so only the recessive was at work.

I've got a spot of red hair that almost certainly came about the same way.

Hey, I also have one attached earlobe and one unattached. I have a theory that I am a chimera. Google the disease Chimerism, it is really interesting. You might actually be two people in one. I have other symptoms, such as my skins being slightly different colors on the right side of my body versus the left side. My hair also is different on the right side versus left side. One of my eyes is nearsided while the other is farsided. It is actually pretty cool. :)

I have that exact some problem. Unlike you i haven't been proud of it. I always thought there was something seriously wrong with me and so did everyone else around me!! Have you found out anything else about this topic???

It's not a disease. And as far as I know, many people who have these bonus chromosomes don't even realize they do.

There is another possibility - some individuals are actually two individuals that merged as embryos: fraternal twins become one person. Parts of the individual are genetically distinct. First discovered, I think, when a CSI investigations decided that a child's mother was actually the aunt (child produced from one individual's ovaries, cell sample taken from the other individual's cheek). And there was NO question that she had given birth to the child.
