Answer 1

The real father could be identified by the method of DNA fingerprinting.

Explanation:

DNA Fingerprinting:

➣The sequence of DNA of each human being is 99.9 percent similar. It is the 0.1 percent difference which makes every individual unique.

➣ DNA fingerprinting involves identifying these differences in the repetitive DNA regions of the DNA sequence. Here a small stretch of DNA is repeated multiple times.

➣ By density gradient centrifugation, the repetitive DNA is separated from the bulk DNA. The major peak is formed by the bulk DNA and satellite DNA forms the small peaks.

➣ The satellite do not co de for any protein but has a high degree of polymorphism and form a large portion of the human genome and hence forms the basis of DNA fingerprinting.

➣ DNA is taken from tissues such as saliva, blood, hair follicle, sperm, bone, skin etc for DNA fingerprinting.
