People with two copies of the sickle cell gene have the disease. People who carry only one copy of the sickle cell gene do not have the disease, but may pass the gene on to their children. Abnormal hemoglobin, called hemoglobin S, causes sickle cell disease (SCD). The problem in hemoglobin S is caused by a small defect in the gene that directs the production of the beta globin part of hemoglobin. This small defect in the beta globin gene causes a problem in the beta globin part of hemoglobin, changing the way that hemoglobin works.
Answer:
Answer is clearly explained in explanation.
Explanation:
In evolutionary biology, the convergent evolution is the process by which organisms from different evolutionary lines independently develop similar adaptations or features in response to similar environmental conditions. North American cacti and African euphoria are clear examples of this concept. Both types of plants have developed thick, juicy stems that are ideal for storing water and protecting thorns, and both are well suited to deal with the rain scarcity and dry climate of the desert regions. The two plant species belong to different plant families and are distant relatives in the phylogeny of flowering plants; However, their common characteristics indicate that they are the product of a converging evolution. The convergent development has enabled the two species of plants to develop similar adaptations to facilitate their survival in the hot and dry desert environment in which they live.
