Class 12th Chemistry, Question -A sample of hair and blood was found at two sites. Scientists claim that the samples belong to same species. How did the scientists arrive at this conclusion?

Question 26:A sample of hair and blood was found at two sites. Scientists claim that the samples belong to same species. How did the scientists arrive at this
conclusion?

The correct answer is – Comparative analysis of DNA is a commonly used technique to determine if two samples of biological material, such as hair and blood, belong to the same species. DNA is unique to each individual and can be used to identify an individual or determine if two samples are from the same individual or species. To determine if the hair and blood samples belong to the same species, scientists would extract DNA from both samples and compare the DNA sequences using techniques such as Polymerase Chain Reaction (PCR) and gel electrophoresis. If the DNA sequences from both samples match, then it is likely that the samples belong to the same species. Scientists may also use other techniques, such as comparing the morphology or physical characteristics of the hair and blood samples, to help identify the species. However, DNA analysis is generally considered the most reliable method for species identification.
