Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Two humans believe they are related. Which would be the best technique to determine if they are related?
A
testing blood types
B
comparing DNA
C
examining karyotypes
D
testing for genetic disorders
Explanation: 

Detailed explanation-1: -Comparative genomics is a field of biological research in which researchers use a variety of tools to compare the complete genome sequences of different species. By carefully comparing characteristics that define various organisms, researchers can pinpoint regions of similarity and difference.

Detailed explanation-2: -DNA Fingerprinting Although more than 99.1% of the genome is the same throughout the human population, the remaining 0.9% of human DNA shows variations between individuals. These variable DNA sequences, termed polymorphic markers, can be used to both differentiate and correlate individuals.

Detailed explanation-3: -The methods used for DNA analysis in genetic engineering are: Polymerase chain reaction (PCR) Northern blotting. Southern blotting.

Detailed explanation-4: -The chimpanzee and bonobo are humans’ closest living relatives. These three species look alike in many ways, both in body and behavior.
