A boy moves to another country to live with his father. Years later, the boy decides to move back to live with the woman who raised him. Immigration officials suspected that the boy was the woman’s nephew, not her son, and therefore not legally entitled to residency. Based on the DNA fragments, is it possible that she is the boy’s mother? Yes or No

The question is incomplete as it does not have the attached DNA gel which has been attached.

No

Explanation:

In the given question, the DNA of the boy was compared with the DNA samples of his father and mother.

The DNA if these people were collected and PCR was performed to duplicate the DNA. These DNA samples were then analysed on the Gel electrophoresis in which the bands were visualized with the UV light.

In the band, we observe that the size of the DNA fragments was not similar to the DNA sample of the women but a band was of similar size to the father.

Since the bands are of different size of the boy when compared to the mother, therefore, the women are not the mother of the boy.

Thus, No is the correct answer.

the fossil record provides evidence of a common ancestor to many species.
