Genome maps provide the DNA sequences of chromosome. Some scientist have compared the genome maps of a hedgehog and a sloth.What do these genome maps allow the scientists to determine?

A. The color patterns of the offspring of each species

B. How much the size ranges of the two species differ

C. The methods of protein synthesis that species uses

D. How closely related the two species are to each other

Genome maps of every individual is unique. Genome map is the order of sequence of nucleotide which is present in an organism. Comparison of genome map allow the scientist to know how much closely related two organisms are.

The map of two individuals of the same species is almost the same. Similarly, the two same species have a more similar genome map than two distantly related species because they share most recent common ancestor.

For example, humans and chimpanzees are more similar than other apes so 96% of the genome are identical between them. So the right answer is D.
