Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Genome maps provide the DNA sequences of chromosomes. Some scientists 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 each species uses
D
How closely related the two species are to each other.
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -Genome mapping is used to identify and record the location of genes and the distances between genes on a chromosome.

Detailed explanation-3: -How can the ancestry of the lizards from the genus Gallotia be best supported by this information? The common ancestor of the lizards probably came from Africa.

Detailed explanation-4: -Which statement provides the best evidence that Ambulocetus natans is an ancestor of Basilosaurus isis? Homologous structures occur in each fossil.

Detailed explanation-5: -Answer and Explanation: The least related organism of the three is Notophthalmus viridescens, otherwise known as the Eastern newt. It can be seen that this organism belongs to a different order than the other two organisms, making it less related than the others.
