The trait for sickle cell anemia in humans shows a recessive pattern of inheritance. The alleles for sickle cell anemia in two individuals are shown below.


Sickle Cell Anemia Alleles
Individual Alleles
C Hh
D hh


Which individual(s) would show observable sickle cell anemia?
Only C
Only D
Both C and D
Neither C nor D

Answer 1

Answer:

The answer is 'Only D'

Explanation:

It says it is a recessive oattern of inheritance, so an individual needs to have both alleles for this disease (hh) in order to show it.

Hope this helped!!!

Answer 2

Sickle cell anemia is a recessive inheritance so it will be visible in homozygous recessive conditions, i.e., in hh individuals.  The correct option is B.

What is sickle cell anemia?

Sickle cell anemia are among the many inherited disorders known collectively as sickle cell disease. It has an effect on the shape of red blood cells.

Red blood cells typically last about 120 days before needing to be replaced. However, sickle cells typically die within 10 to 20 days, resulting in a shortage of red blood cells (anemia).

Sickle cell anemia is a recessive inheritance so it will be visible in homozygous recessive conditions, i.e., in hh individuals.

Thus, the correct option is B.
