Question
Which disorder or disease has alleles that are co-dominant with each other?
- Hemophilia
- Sickle cell anemia
- Cystic fibrosis
- Huntington's
Hint:
Malaria can also cause this disease.
The correct answer is: Sickle cell anemia
- Sickle cell anemia is an example of codominance
- Codominance refers to expression of both the alleles of a gene
- The individuals with sickle cell can have homozygous or heterozygous genes
- Heterozygous gene containing individuals will have normal hemoglobin and abnormal "S" hemoglobin
- Homozygous gene containing individuals carry abnormal hemoglobin
- Sickle cell disease is a medical condition where the Red Blood Cells loses its normal shape
- The disease can be caused due to malaria or due to genetic disorder

Which disease or disorder causes people to have abnormal hemoglobin?
- Disorder or disease associated with hemoglobin causes anemia
- In sickle cell anemia, the individual posses an altered "S" hemoglobin causing the RBCs to alter its shape
- The RBCs with "S" hemoglobin become rigid and sickle shaped with inability to transport gases, resulting in anemia
- Hemophilia is the disorder due to deficiency of clotting factors

Parallelogram law is used when _______
In parallelogram law of vector addition, it says that if we place two vectors so they have the same initial points(the tails are connected) and then complete the vectors into a parallelogram, then the sum of the vectors is directed diagonal that starts at the same point as the vectors.
