Excision is the right answer :)
It is a very interesting question - the technology is real and the research on eDNA published in a journal in 2017.
eDNA stands for enviornmental DMA sampling. It allows scientist to test water samples for the presence of the DNA of the invasive fish species. It is more effective than traditional methods of sampling because it does not require trapping or sighting of the invasive species. Water samples can be collected anywhere any time and the DNA results are as accurate and detailed as collected from the invasive species themselves. It provides a complete picture of what invasive species are there.
Humans usually have 46 chromosomes. Monkeys, chimps, or other organisms related closely to them: they have diploid number of 48 chromosomes.
(Future reference: Haploid means half, half the # of chromosomes in the nucleus. Diploids means duplicate, COMPLETE necessary set of chromosomes).
Hope it helps!! :)
