*Sickle cell disease is a constitutional corpuscular hemolytic anemia related to an abnormal structure of the globin chain. It is an autosomal recessive disease, which means homozygosity is necessary to fully express the illness.
*It corresponds to the synthesis of an abnormal hemoglobin, HbS, which is different from normal Hb (HbA).
*The S allele (located in the chromosome 11), responsible for the anomaly, is especially widespread in the African continent, it is also found in other regions of the Mediterranean.

Answer:
Asexual reproduction is through the formation of asexual spores. They are produced by one parent only and are genetically identical to that parent (Mitosis).
Sexual reproduction in the fungi has three stages plasmogamy, karyogamy, and meiosis.
Explanation:
AR: Spores may be dispersed by moving water, wind, or other organisms. The spores far from the parent organism. This helps to ensure that the offspring will not have to compete with the parent for space or other resources.
SR: Sexual reproduction occurs when spores from two parents fuse and form a zygospore.
