A scientific argument will be considered invalid if the evidence supporting the argument is based on independent data.
If you are only referring to a single scientist or a single study conducted on a certain topic, it means that it hasn't been researched enough for the argument to be reliable. Every scientist needs to refer to other studies and other scientists and their work if they want their arguments to be valid.

12345 [234]

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

Answer:

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.
