The word is scientifically termed as Peristalsis.
Answer:
Cloning may be defined as the process by which the genetically identified individual of the organism can be created artifically or naturally. Aseual reproduction results in the formation of clone.
The microsatellite analysis is used to prove that snuppy is a clone. Microsatellites are the highly variable DNA sequences repeats that has variable loci and considered at population level. The two alleles are possible for the one microsatellite locus. After comparing the alleles it has been found that snuppy has exactly the same genetic material as the surrogate mother, afghan. This completely determines that snuppy is a clone of afgan.
So the dark butterfly camouflages better on the tree. Where as the white one can clearly be seen and identified. A predator will also easily spot it and kill it. The dark butterfly has evolved over time to the color that it is, to best help it survive. This is also shown in the tread on the graph.
Hope this helps!!
If you are implying one these choices not needed for survival it would be parents only when you can survive on your own (I'm not that sure but I hope this helped the slightest but)
It is the comparison of the nucleotide sequences in DNA
