Which of the following best describes evidence from biochemistry that a geneticist studying evolutionary relationships might use to determine that two species are not closely related?
each species has a different reproductive mechanism.
one species has genetic material that does not contain nitrogenous bases.
similar gene sequences in each species code for different proteins.
the two species have different numbers of chromosomes.

Option D , The two species have different numbers of chromosomes.

Explanation:

Evolutionary differences arises from the variation in genetically material quality and quantity.Two species which are closely related may or may not have exactly same number of chromosomes. Thus, in case if the number of chromosomes vary in two species, then it is does not provide a strong evidence that these species are closely related.

hence, option D is correct
