Human chimeras do exist. A chimera is an individual with two or more genetically distinct cell lines within their body. This can occur naturally, for example, through the absorption of a twin during early development. Chimerism can also be a result of organ transplants or bone marrow transplants, where the recipient’s body incorporates donor cells.
FAQs & Answers
- What is a human chimera? A human chimera is an individual with two or more genetically distinct cell lines, often resulting from twin absorption or transplants.
- How do human chimeras occur? Chimeras can occur naturally or through medical procedures like organ and bone marrow transplants, where the host incorporates donor cells.
- Can human chimeras have different blood types? Yes, depending on the different cell lines in their body, human chimeras can indeed possess different blood types.
- Are human chimeras common? Human chimeras are rare but do exist, with more cases likely undetected due to their subtle presentations.
