Record the results for the hematocrits. Identify the hematocrit that is considered within normal range. For the other two hematocrit tubes, comment on the possible conditions that would cause the value to be different from normal. Explain what causes the average value of the hematocrit to be higher in males than in females. A person had severe pain episodes, several bouts of infections, signs of damage to vital organs, low RBC count and hemoglobin, and fatigue. A smear preparation of the blood showed deformed RBC. Give a brief account of the disorder, cause, and how it is inherited.

Solution

1.causes for hematocrit average value higher in males than in females : due to the release of the testosterone harmone which is also\" responsible for the stimulation of erythropoitein\" secreted by kidneys.so males have more hematocrit than females.

2.according to the information it is a disorder named \"sickle cell anemia\"

the normal rbcs are disc shaped where as these are sickle shaped due to low oxgen levels in rbcs leading to defective rbcs which form as long rods and into abnormal sickle shapes.these cannot be easily passed through the vessels as these are sickle shaped and block the flow and cuttoff the oxygen supply to tissues.so the lack of oxygen leads to organ damage and severe pain.

the normal life span of rbcs is 120 days where as these sickle rbcs live only upto 10-20 days so causes chronic anemia

INHERITANCE : the two genes from one parent must be inherited from one parent inorder to have disease.if only one gene of sickle cell and another normal gene then there is no or less probability of having disease.if two genes from both parents are sickle genes then the person is affected with disease.
