Two Sets of DNA
Genetics is typically a straightforward concept, but there are exceptions, as with everything in life. Have you heard of Chimeras? They are organisms that possess two distinct sets of DNA. Although this term is frequently associated with animals, it can also be applicable to humans in rare cases. This woman is an example of human chimerism, exhibiting two different skin pigments and two distinct red blood cell lineages.
At first glance, it may be difficult to detect the difference, but upon closer inspection, it appears as if she has acquired a captivating tan while sunbathing.
