Is it posible for a human to have 2 separate types of DNA? Saw something about this and they were called kimeras only 48 cases in the world. Cant confirm this information until now! any info apreciated!

Hmmm… Chimeras are an organsim composed of two separate populations of cells (derived from two distict orgnaisms/individuals) ….

check out the subtitle "Parasitic twin" at this url: http://en.wikipedia.org/wiki/Fraternal_twins

yes it’s possible –> chimeras are the already called examples, but there are numerous mosaics in this world (namely all the females). They have populations of cells expressing different chromosomes.

There was actualy a very good
documentary about this.

These people were suposed to be one of twins
but the other twin and them fused together
at cellular division.. Some babies are unfortunate
to be born both male and female and both light
and darker skin. (bilaterally)
And there was profiled the case of a woman who
had her children taken a way because blood tests
revealed her dna did not match her children.
However with chimeras dna from other twin would
be found from a different source such as internal organs.

Very facinating!!
