DAT Test

Hi. I've got an interesting question.

 

In the CSI rebroadcast 2-3 weeks ago this dialogue about DNA test results

occurred.

Gil Grissom (supervisor) speaking to Greg, the technician: "Do you have the

DNA results?"

Greg: "yes, there are 7 out of 13 matches"

Grissom: "that means they are related"

Greg: "more than that, they are parent and child"

Grissom: "yes"

 

a. Why is this conclusion wrong?

b. What should the dialogue be to reach this conclusion? Alternatively, what

other conclusion would these data support?

First off, you have to define "matches" I assume that it means gene banding matches on an electrophoresis gel, but what gene are they referring to? Without this inforamtion, the word "matches" means virtually nothing.
