Answer: The type of inheritance shown by the gene that control sickle cell anaemia is autosomal recessive inheritance
Explanation: Autosomal recessive inheritance means that there is mutation in two copies of the gene in a cell. Sickle cell anaemia is a condition caused by a single point mutation in the two beta chains of haemoglobin. Haemoglobin is a protein in the red blood cells responsible for oxygen transport to the cells. The mutation is caused by substitution of valine in place of glutamate at the sixth position of the two beta chains of haemoglobin.
Every individual has two copies of almost every gene, one from the mother, and one from the father. The autosomal recessive inheritance pattern of sickle cell gene means that for an individual to manifest outwardly as sickle cell, the two copies of the gene inherited from the parents are mutated.
The sugar found in DNA is deoxyribose.

Messenger System, which means, cells signal to each other what molecules have
been released that will trigger a physiological reaction. </span>

This phenomenon is activated after the ligand (ion or molecule) is bonded to its receptor
(protein molecule), creating a variation that causes a chain-reaction, that will
finally activate the Second Messenger. The latter will activate intercellular
molecules that will be able to control the cell’s activity. </span>
Answer:
Evolution, of course is the process of change in all forms of life over generations and evolutionary biology is the study of how evolution occurs. Biological populations evolve through the changes in the organisms' observable traits. All life on the planet exists because it evolves to best fit the environmental conditions and those who adapt best, pass on those characteristics to their offspring. In other words, descent with modification.
