Question
A group of Maryland team of doctors last year performed the world's first transplant of a heart from a genetically altéred pig into another dying man. David Bennett survived two months before that heart failed. Why is it possible for the pig organ be used in a human? There are little to no variation in the two organism. Pig and human share identical DNA sequences. Pig and human share similarities in their DNA sequences. Pig and human share the same DNA

Answer
The correct answer is:Pig and human share similarities in their DNA sequences.Step by step explanation:1. The statement "There are little to no variation in the two organism" is incorrect because although pigs and humans do share some physiological and anatomical similarities, there are indeed variations between the two species.2. The statement "Pig and human share identical DNA sequences" is incorrect because each species has its own unique DNA sequence. No two species have identical DNA.3. The statement "Pig and human share the same DNA" is incorrect for the same reason as above; each species has distinct DNA.4. The correct statement is "Pig and human share similarities in their DNA sequences." This is because while the DNA sequences are not identical, they are similar enough that pigs can be considered as potential organ donors for humans after genetic modification. Pigs have organs that are similar in size and function to human organs, and with genetic alterations, the risk of rejection by the human immune system can be reduced, making xenotransplantation a possibility.Final Answer: Pig and human share similarities in their DNA sequences, which is why it is possible for a pig organ to be used in a human after genetic modification.
