23. “DNA fingerprinting” is a recently-introduced biochemical procedure that uses a pattern derived from a person’s genetic material to match a suspect’s genetic material against that of a specimen from a crime scene. Proponents have claimed astronomically high odds against obtaining a match by chance alone. These odds are based on an assumption that there is independence between the different characteristics represented by a single pattern.

Which one of the following, if true, casts the most doubt on the claim of the proponents of DNA fingerprinting?

(A) The large amount of genetic material that people share with all other people and with other animals is not included in the DNA fingerprinting procedure.

(B) There is generally accepted theoretical basis for interpreting the patterns produced by the procedure.

(C) In the whole population there are various different subgroups, within each of which certain sets of genetic characteristics are shared.

(D) The skill required of laboratory technicians performing the DNA fingerprinting procedure is not extraordinary.

(E) In the investigation of certain genetic diseases, the techniques used in DNA fingerprinting have traced the transmission of the diseases among the living members of very large families.

答案是C。我看不懂段落中反对者的意思，因此也就看不懂为什么选C。 哪位NN帮我解释一下？

1. I think that "undesirable" is a typo.

2. There is no statement from 反对者 in the question. "Proponent" means opposite. C disputes the assumption that the different characteristics are independent.

1、难怪，我也觉得有错，觉得意思应该相反才对。
2、我真糊涂，一直把proponent当“反对者”来理解，于是就怎么看怎么不懂。这下就好理解了。多谢！
