Imagine you do DNA fingerprinting in a forensics lab. You obtain six samples from a crime scene and use them to make the DNA fingerprints shown below
Which two samples are most likely to have come from the same person?
1
2
3
6
O A. No two samples came from the same person.
OB. 4 and 5
O C. 2 and 4
O D. 1 and 6

D

Explanation:

Because if you look at the pattern and location of each shading you cant tell that they are the exact same. No 2 people have the same fingerprint hence that has to be from the same person.

explanation:

children tend to take more after their grandparents more than their parents. it’s the dna you received that was passed down to you somewhere in your family. maybe one of your grandparents had/has straight hair and you might have gotten it from them.
