Answer:
The correct answer will be- genes can be transferred among species
Explanation:
Green fluorescent protein or GFP is a protein which is naturally expressed in a jellyfish called Aequorea victoria. The protein absorbs the light and emits it in green color.
Scientist isolated the gene of the protein from the jellyfish in the 1960s and transferred it to the genes of the other species like bacteria or mice. This shows that although the species can be isolated from the reproduction by reproductive barriers but the molecule containing code of life can be transferred easily without any barrier.
Thus, genes can be transferred among species is the correct answer.
