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 an example of an autosomal dominant disease A Huntington's disease and neurofibromatosis type 1 or B Alzheimer's Disease and Heart Disease?
A. Huntington's disease and neurofibromatosis type 1 are examples of autosomal dominant diseases. These conditions are caused by a single copy of a mutated gene on an autosome (non-sex chromosome) and can be passed down from one affected parent to their offspring with a 50% chance of inheritance.
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 is a genetic disorder that cannot be detected by karyotyping?
Karyotyping looks at the complete set of chromosomes. It can detect large-scale abnormalities, such as missing/extra chromosomes or whether large pieces of chromosomes have been rearranged. It cannot detect any of the many, many genetic disorders which are caused by a single gene, several genes or gene interactions. Examples of these would be cystic fibrosis, sickle-cell disease and dwarfism.
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.
What disease is caused by a single mutated gene?
One example of a disease caused by a single mutated gene is cystic fibrosis. This genetic disorder is caused by mutations in the CFTR gene, which leads to the production of thick, sticky mucus that can clog the lungs and obstruct the pancreas. Symptoms often include respiratory issues, digestive problems, and increased susceptibility to infections. Other examples include sickle cell anemia and 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.
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.
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 is single gene trait?
A single gene trait is a specific characteristic or phenotype that is influenced by the expression of a single gene. This means that the presence or absence of a particular trait is determined by variations in one specific gene. Examples include earlobe attachment, hair color, and tongue rolling.
What are two examples of genetic disease?
A few examples of genetic diseases are:Chromosomal abnormalitiesSingle gene defectsMultifactorial problemsTeratogenic problems
