Define a genetic mutation and state the types of genetic mutations?
A genetic mutation is a change in the DNA sequence that can affect an organism's traits. The types of genetic mutations include point mutations (substitution, insertion, deletion), frameshift mutations, and chromosomal mutations (deletion, duplication, inversion, translocation).
Is anemia a genetic disorder?
Anemia is a broad disorder that literally translates as 'no blood'. In medical practice, anemia is a condition in which there are insufficient normal red blood cells to provide oxygen to the body tissues. Anemia can be caused by a wide variety of things: large volume blood loss, infection, cancer and toxins can all result in various types of anemia. There are also genetic causes of anemia. Two commonly discussed genetic anemias are sickle cell anemia and hemophilia-related anemia. Sickle cell anemia developed in Africa, where malaria parasites are common. A heterozygous individual has about 15% abnormal red blood cells that are crescent-shaped and don't transport oxygen well. Hemophilia was traced to a point mutation in the English royal line in the Middle Ages, which then spread throughout Europe via marriage among the royal houses. Hemophilia actually results in blood that does not clot properly, which can result in anemia due to chronic blood loss through hemorrhages.
What if the cellular process that carries out hereditary instructions would be affected by a mutation?
Depending on the type of mutation, this could be harmless, or it could be harmful and even lethal.For example, a point mutation changes one base in a codon. Since most amino acids have more than one codon, this mutation may still code for the same amino acid. For example, both TTT and TTC codons code for the amino acid phenylalanine, so if TTT was mutated to TTC, the mutation would have no effect.However, in sickle cell anemia, a life-threatening genetic disorder, is also caused by a point mutation, in which the codon CTC is mutated to CAC. The codon CTC codes for the amino acid glutamine, and CAC codes for the amino acid valine. This change in just one codon causes the hemoglobin molecule to have an altered structure, which causes the red blood cells carrying the mutated hemoglobin molecule to be stiff and have a concave (sickle) shape. The sickle-shaped cells clog blood vessels and do not transport oxygen effectively, which causes pain and damage to the organs, shortening the lifespan by about 30 years. A person must inherit the mutated gene from both parents in order to be affected.Source: http://learn.genetics.utah.edu/content/disorders/singlegene/sicklecell/There are other types of mutations, such as frameshift mutations, and chromosomal mutations that can negatively impact the affected organism.
The blood disorder characterized by anemia?
The blood disorder characterized by anemia is known as iron deficiency anemia. It occurs when there is a lack of iron in the body, leading to insufficient production of red blood cells and resulting in symptoms like fatigue, weakness, and pale skin. Iron deficiency anemia can be treated with iron supplements and dietary changes to increase iron intake.
Do humans have different types of cells all the same shape?
Yes they are. There are many dirrerent shapes such as rod, bacilli, and many others.

What kinds of anemia are there?
The different types of Anemia include: . Iron Deficiency Anemia - Is causes by blood loss, or lack of iron in the diet. . Pernicious Anemia - It occurs when the body is unable to absort Vitiman B12 . Folic Acid Deficiency Anemia - It occurs when there is a lack of folic acid in the diet. . Hemolytic Anemia - It is an inherited or acquired type of anemia that causes the red blood cells to be deformed, so the body breaks down the red blood cells too fast. . Sickle Cell Anemia - Inherited disease that occurs when the red blood cells are sickle shaped. The hemoglobin doesn't work right, the shape of the red blood cells causes them to clog the blood vessels and break down easily.
What are the different types of sickle cell disease and how do they differ from each other?
There are several types of sickle cell disease, including sickle cell anemia, sickle beta thalassemia, and sickle cell-hemoglobin C disease. These types differ based on the specific genetic mutations that affect the hemoglobin protein in red blood cells. Sickle cell anemia is the most common and severe form, where individuals have two copies of the sickle cell gene. Sickle beta thalassemia and sickle cell-hemoglobin C disease are milder forms that result from different combinations of genetic mutations. Symptoms and complications can vary among the different types of sickle cell disease.

Does HEmoglobin mutation cause disease?
Yes, hemoglobin mutations can cause diseases, most notably sickle cell disease and various types of thalassemia. These mutations can alter the structure and function of hemoglobin, leading to impaired oxygen transport and various complications. In sickle cell disease, for instance, abnormal hemoglobin causes red blood cells to become rigid and sickle-shaped, leading to blockages in blood vessels and pain. Thalassemias result in reduced hemoglobin production, leading to anemia and other health issues.
What are types of anaemia?
there are over 400 types of anemia. such as sickle cell, G6PD anemia, iron deficiency, B12 deficiency, aplastic, megaloblasic/pernicious, hemolytic, hemoglobin, Thalassemia, Excessive destructions of red blood cells and many more. 3 major types of anemias: low RBC anemias Low hemoglobin content abnormal hemoglobin
How does one avoid getting aenima?
Iron deficiency anemia can be avoided by eating a sufficient amount of iron. Sources of iron include meats and spinach. Other types of anemia, such as sickle cell anemia and pernicious anemia is a result of disease processes and genetics and are not preventable.
How is gene involved in sickle cell anemia different from the genes for pea plants that mendel studied?
The gene involved in sickle cell anemia is the HBB gene, which encodes the beta-globin subunit of hemoglobin in humans and is associated with a specific mutation (a single nucleotide substitution) that leads to the disease. In contrast, the genes Mendel studied in pea plants, such as those for seed shape or flower color, are typically characterized by simple Mendelian inheritance patterns. While both types of genes follow genetic principles, the complexities of human genetics, including multiple alleles and interactions, make sickle cell anemia a more intricate trait than the traits Mendel observed in peas.

What are all the types of anemia in livestock?
There are 3 types of Livestock anemia. Infectious anemia, Nutrition anemia, and bovine anemia. Bovine anemia is found mostly in cows.
How many types of anemia are here?
There are several types of anemia. The term means without blood. It could be caused by excessive bleeding or damage to the bone marrow. Anemia is one of the most common disorders of the blood. It can be due to excessive blood loss or hemorrhage. Or deficient red blood cell production. Anemia can be classified in several ways: macrocytic anemia, normocytic anemia, microcytic anemia. Some of the more familiar ones are: pernicious anemia due to lack or low B12, iron deficiency anemia due to lack of iron, thalassemia, lead toxicity anemia, hypothyroidism, aplastic anemia, sickle cell anemia, Rh disease, and renal infection among others.
