How do genetic disorders occur in humans?
Genetic disorders can be caused by a mutation in one gene (monogenic disorder), by mutations in multiple genes (multifactorial inheritance disorder), by a combination of gene mutations and environmental factors, or by damage to chromosomes (changes in the number or structure of entire chromosomes.
What are genetic disorders that involve more than one defective gene?
Some examples of genetic disorders involving more than one defective gene are cystic fibrosis, which is caused by mutations in the CFTR gene and other modifier genes; and certain types of neurofibromatosis, which result from mutations in both the NF1 and NF2 genes. These disorders demonstrate the complexity of genetic inheritance and the interactions between multiple genes.
What causes hematology blood disorder?
"hematology" means the study of blood. there are thousands of diseases of blood and as for the causes of "blood disorders," there are thousands of those too, including genetic diseases, nutritional deficiencies, cancers, and infections.
What are some easy genetic disorders to research and understand?
Some easy genetic disorders to research and understand include Down syndrome, cystic fibrosis, and sickle cell anemia. These disorders have well-documented genetic causes and symptoms that are relatively straightforward to comprehend.
When women drink or smoke during pregnancy does it cause the baby to have genetic disorders?
Drinking or smoking during pregnancy can increase the risk of birth defects or developmental issues, but it does not directly cause genetic disorders in the baby. Genetic disorders are typically caused by changes or mutations in the baby's DNA that are inherited from the parents or happen spontaneously.
Why can females but not males carriers of sex linked genetic disorders?
Several genetic disorders are caused by genes on the X chromosomes.
Mental retardation caused by what disorders is often apparent from infancy?
If retardation is caused by chromosomal or other genetic disorders, it is often apparent from infancy.
Are genetic disorders contagious or caused by germs?
Genetic disorders are not contagious because they are caused by changes in a person's DNA that are passed down from parents. They are not caused by germs, which are microorganisms like bacteria and viruses that can be transmitted from person to person.

What are 2 genetic disorders caused by point mutation?
sickle cell anaemia, thalassaemia
How can I identify and prevent the occurrence of genetic disorders caused by duplets in DNA sequences?
To identify and prevent genetic disorders caused by duplications in DNA sequences, genetic testing can be used to detect the presence of duplications. Additionally, genetic counseling can help individuals understand their risk of passing on these disorders to their children. In some cases, pre-implantation genetic diagnosis can be used to select embryos without duplications before pregnancy.
What movement disorders are caused by inherited genetic defects.?
Movement disorders caused by inherited genetic defects include Huntington's disease, spinocerebellar ataxias, dystonias, and certain forms of Parkinson's disease. These disorders result from specific genetic mutations that can be passed down from parents to their children. Symptoms may vary depending on the specific disorder but often involve involuntary movements, tremors, or muscle stiffness.
What is the medical term meaning Condition caused by defective genes?
The medical term for a condition caused by defective genes is genetic disorder. These disorders are caused by abnormalities in an individual’s DNA and can result in a wide range of symptoms and health issues.
Red-green colorblindness and hemophilia are two human genetic disorders that are caused by?
X-Linked Inheritance
Is hemophilia caused by inbreeding?
No, hemophilia is a genetic disorder caused by a mutation in the genes responsible for blood clotting, and it is not directly caused by inbreeding. Inbreeding can increase the likelihood of inheriting genetic disorders, including hemophilia, if the mutation is present in the family's gene pool.
What the caused of mental illness?
The majority of psychological disorders are thought to be caused by a complex combination of biological, genetic (hereditary), familial, and social factors or biopsychosocial influences.
