diseases include food allergies, hay fever, atopic dermatitis and allergic
asthma. Symptoms may include, a runny nose, shortness of breath, swelling red

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.
