What disease is caused by a dominant allele of a single gene?
Huntington's Disease
What Does a particular trait result from the expression of a single gene?
Huntington's disease is a perfect example of a single gene trait. A mutation in this allele causes Huntington's disease in later life. A dominant trait. Widows peak us another. Any gene that controls the total expression of a trait is an allele defined as a single gene trait.
Which of the following is the first step in gene therapy?
Identifying the faulty Gene. Identifying the faulty Gene that causes the disease.
What are some examples of multi-gene traits?
height, hair color, eye color, diabetes, heart disease, cancer these are more common..mendelian traits are more rare and easier to predict
What is a gene where is it located and how can mutations to a gene affect an organism?
A gene is hereditary (gotten from mom and dad) unit consisting of a sequence of DNA that occupies a specific location on a chromosome. Mutations are changes in the DNA.A single mutation can have a large effect and some have no effect. It depends on which base or bases have changed. If the change is in what is called a coding sequence then the result can be a different or non-functioning protein.Sickle cell anemia and Polycystic kidney disease are examples.
What disease is caused by a dominant allele of a single gene?
Huntington's Disease
What are bad examples for sex linked traits?
Height, eye color, many behavioral traits and many single gene deleterious mutations that lead to disease, such as Huntington's disease.
What is the difference between single-gene traits and complex traits?
Single gene diseases only effect one typeof gene where im a complex genetic disease many genes are effected. An example of a single gene diseas is sickle cell anemia. Cancer would be an eexample of a complex gene disease.
Is a non mendelian trait controlled by one gene?
A non Mendelian trait can be controlled by one gene. When a trait is controlled by one gene it results in genetic disorders. Examples of disorders due to single gene inheritance - Huntington disease, Fragile-X syndrome.
What Does a particular trait result from the expression of a single gene?
Huntington's disease is a perfect example of a single gene trait. A mutation in this allele causes Huntington's disease in later life. A dominant trait. Widows peak us another. Any gene that controls the total expression of a trait is an allele defined as a single gene trait.
Sickle cell disease is caused by a?
small change in the DNA of a single gene
Is Huntington's Disease a gene mutation?
No, it's caused by a single point mutation of a gene.
Punnett square examples for Huntington's disease?
You could use a Punett Square for Huntington's disease, but why bother? If one parent has the disease, there is a 50% chance that a child will get it. The other factor involved is that with gene therapy advancing so fast, it is possible that it will be possible to replace a single gene in a particular chromosome in a baby born today before that baby reaches 30 years of age. Since Huntington's disease involves one gene on one chromosome, it should not be much of a problem.
What is Genetic order?
Monogenetic disorders are caused by a mutation in a single gene. The mutation may be present on one or both chromosomes (one chromosome inherited from each parent). Examples of monogenic disorders are: sickle cell disease, cystic fibrosis, polycystic kidney disease, and Tay-Sachs disease.
What are two examples of genetic disease?
A few examples of genetic diseases are:Chromosomal abnormalitiesSingle gene defectsMultifactorial problemsTeratogenic problems
Is huntington's disease determined by multiple alleles?
No. This is a single gene disorder. If at least one allele has the huntington's mutation, the person will eventually develop the disease.
What is a cause of a genetic disease?
What is a genetic disease?A genetic disease is any disease that is caused by an abnormality in an individual's genome. The abnormality can range from minuscule to major -- from a discrete mutation in a single base in the DNA of a single gene to a gross chromosome abnormality involving the addition or subtraction of an entire chromosome or set of chromosomes. Some genetic disorders are inherited from the parents, while other genetic diseases are caused by acquired changes or mutations in a preexisting gene or group of genes. Mutations occur either randomly or due to some environmental exposure. What are the different types of inheritance?There are a number of different types of genetic inheritance, including the following four modes: Single gene inheritanceSingle gene inheritance, also called Mendelian or monogenetic inheritance. This type of inheritance is caused by changes or mutations that occur in the DNA sequence of a single gene. There are more than 6,000 known single-gene disorders, which occur in about 1 out of every 200 births. These disorders are known as monogenetic disorders (disorders of a single age). Some examples of monogenetic disorders include:cystic fibrosis,sickle cell anemia,Marfan syndrome,Huntington's disease, andhemochromatosis.
