Question

Jeanine believes that she was cheated by the breeder who sold her a "supposedly" pure-bred golden retriever, so her vet sends a sample of Jeanine's dog's blood to the laboratory for analysis. What method would the laboratory employ to determine the dog's pedigree?

A. Polymerase chain reaction (PCR)
B. DNA fingerprinting
C. Gel electrophoresis
D. DNA sequencing.

Answer 1

The laboratory would use DNA sequencing to determine the dog's pedigree by analyzing the sequence of the dog's DNA.

Step-by-step explanation:

The laboratory would employ DNA sequencing to determine the dog's pedigree. DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule. By analyzing the sequence of the dog's DNA, the laboratory can identify specific genetic markers or variations that are characteristic of purebred golden retrievers.
