Some scientists claim that the gene that controls the production of h e m o g l o b I n, is located at the position shown in the

diagram.
What is the best evidence for this claim?
A) Humans without this gene exhibit problem with oxygen binding in their red blood cells.
B) Other organisms that require oxygen have similar genes in similar locations.
C) Nearby genes on the chromosome are thought to control other blood factors.
D) Healthy humans all have this same gene in exactly the same location

Answer:

A) Humans without this gene exhibit problem with oxygen binding in their red blood cells.

Explanation:

Oxygen binds to red blood cells because of their hemoglobin component. It is a protein found in red blood cells.
Each hemoglobin molecule is able to bind to four oxygen molecules.
If the gene controlling hemoglobin production is absent in humans, the red blood cells will not be able to bind to oxygen.
Hence, if the gene given in diagram is removed and it results in difficulty in binding of oxygen to red blood cells, that gene might be involved in hemoglobin production.
