Answer:
Pleiotropy
Explanation:
The single gene responsible for expressing many characters/traits is called pleiotropy. The sickle cell anemia disease is pleiotropic that is caused by HBB gene mutation. The mutation results in multiple traits (consequences) due to single gene mutation.
The RBCs shape changed to sickle shape this results in low energy levels, blood clots, and strokes. The mutation forms HbS (hemoglobin S) from hemoglobin beta globin subunits. Thus, this is an example of <u>Pleiotropy.</u>
Solution:
In children, it is easily found it can cause rickets. Rickets is a rare disease that causes the bones to become soft and bend. In adults, severe vitamin D deficiency leads to osteomalacia. Osteomalacia causes weak bones, bone pain, and muscle weakness.
It happens due to the lack of Calcium.
Yes. This is because natural gases can also come from natural sources like volcanoes and cows. Cows produce tons and tons of methane each year and volcanoes release many greenhouse gasses when they erupt.
