What are genetic disorders caused by?
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, the structures that …
What are the 3 types of genetic disorders?
There are three types of genetic disorders:
- Single-gene disorders, where a mutation affects one gene. Sickle cell anemia is an example.
- Chromosomal disorders, where chromosomes (or parts of chromosomes) are missing or changed.
- Complex disorders, where there are mutations in two or more genes.
What are the 4 types of genetic disorders?
Four of the main types are:
- Single-gene inheritance diseases.
- Multifactorial genetic inheritance disorders.
- Chromosome abnormalities.
- Mitochondrial genetic inheritance disorders.

Which of the following can cause a mutation quizlet?
Mutations can be caused by environmental agents such as ultraviolet light (sunshine), nuclear radiation, or certain chemicals. Other times, mutations occur when a cell copies its DNA during replication in preparation for cell division.
What’s the most common genetic disorder?
What are 4 possible causes of genetic mutation?
What Causes a Gene Mutation?
- a change in one or more nucleotides of DNA.
- a change in many genes.
- loss of one or more genes.
- rearrangement of genes or whole chromosomes.
What are 2 types of gene mutations?
Two major categories of mutations are germline mutations and somatic mutations. Germline mutations occur in gametes. These mutations are especially signifi ca nt because they can be transmitted to offspring and every cell in the offspring will have the mutation. Somatic mutations occur in other cells of the body.
Which of the following is a true statement about of genetic mutations?
The correct answer to this question is B. They always cause a change to an organism’s genotype. Regardless of the cause of the change, a DNA sequence is always altered when it mutates.
What are mutations in biology quizlet?
Mutation. a change in the genetic material of a cell; cause by a mistake during DNA replication. Gene Mutations.
What are the three main causes of mutations?
A mutation is a change in the DNA sequence of an organism. Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection.
What are 3 causes of mutations?
Which of the following best describes genetic mutation?
1 Answer. A genetic mutation is a random change in the DNA that is passed on further generations of cells and or organisms.
What is the best definition of mutation?
What causes mutations in DNA quizlet?
What is mutation answer?
What do u mean by genetic mutation?
Genetic mutations are changes to your DNA sequence that happen during cell division when your cells make copies of themselves. Your DNA tells your body how to form and function. Genetic mutations could lead to genetic conditions like cancer, or they could help humans better adapt to their environment over time.
