When a group of proteins such as interferons and interleukins are released by the t cells, intercellular signals begin the immun
diamong [38]

The cytokine describes the group of proteins such as interferons and interleukins that regulate cell communication, mainly produced by the immune system in normal and pathological conditions.

<h3>What is a cytokine?</h3>

They are messenger molecules with a glycoprotein structure, whose lifetime is short and generally secreted in cascades.

They are produced by different activated cells, responsible for innate and/or acquired immunity, and regulate the immune and inflammatory response.

Therefore, we can conclude that the cytokine describes the group of proteins that regulate cell communication, mainly produced by the immune system in normal and pathological conditions.

Homozygotes with two sickle-cell alleles are selected against because of mortality. However, heterozygotes for sickle-cell allel
grigory [225]

Answer:

Increased frequency of the allele for sickle cell anemia

Explanation:

Sickle cell anemia is fatal in homozygous genotype. The homozygous genotype having two copies of the allele for sickle cell anemia is not favored by natural selection due to its reduced survival success.

However, the heterozygous genotype for sickle cell anemia with one allele for the disease exhibit malaria resistant. The presence of one allele is not fatal for the organisms as the presence of one normal allele ensures the formation of some normal hemoglobin protein and RBCs to support the oxygen delivery to the body parts.

The increased survival success of heterozygous genotype in malaria-prone regions allowed their natural selection. This increased the frequency of allele for the sickle cell anemia in the gene pool of the local population and increased the frequency of heterozygous dominant genotype.
