Osteogenesis imperfecta is dominant or recessive?
Osteogenesis imperfecta is typically inherited in an autosomal dominant pattern, meaning one copy of the mutated gene is enough to cause the condition. However, in some cases, it can be inherited in an autosomal recessive pattern if both parents are carriers of the mutated gene.
The stronger of the two traits which show up in an organism is called a?
dominant trait. It is more likely to be expressed in the phenotype of an organism when it is inherited with a recessive trait.
What gene is always expressed?
Dominant genes will always be expressed however recessive genes would need to be inherited from both parents
When both alleles of gene are different what is individual?
The individual is heterozygous for that gene. This means they have two different alleles for the gene, one inherited from each parent. The individual will express the dominant allele if present.
What is a non example of dominant gene?
A non-example of a dominant gene would be a recessive gene, which only expresses its trait when two copies are present (one from each parent). For instance, if the gene for blue eyes is recessive, a person would need to inherit the blue eye gene from both parents to express that trait. In contrast, a dominant gene, such as one for brown eyes, would be expressed even if only one copy is inherited.
What causes huningtons disease?
Huntingtons disease is a genetic/inherited diesease. It is caused by a faulty allele (a dominant one), which can be inherited by parents. Spontanoius mutations may also occur which would cause the faulty gene and therefore huntingtons disorder.
How many many parents have to have the allele for huntingtons to affect there children?
Either parent. Since HD is carried on a dominant gene, if the gene is inherited from either parent, the offspring will develop HD.
Why is huntingtons disease more common than other serious dominant genetic disorders?
Huntingtons is a genetically inherited disease from a parent. when chromosomes are passed onto a child, the child wont always receive the chromosome containing the gene. But, if they do inherit the gene they will have the disease no matter what, because the disease is dominant. If it was recessive, the child could inherit the disease but not necessarily get the disease.
Is Huntingtons Disease a recessive gene?
Unfortunately, HD is carried on a dominant gene. If one parent has the gene for HD, and the other does not, the offspring has a 50/50 chance of developing HD. However, if you do NOT inherit the gene for HD, you cannot be a "carrier" of HD. The Huntingtons Disease Society of America has more information at their website. You may also contact me through my message board if you need additional information.
When a gene inherited from one parent masks the expression of the gene inherited from the other parent that gene is said to be?
That gene is said to be dominant. Dominant genes will be expressed over recessive genes in a heterozygous individual.
What is the Mode of inheritance hemophilia?
Transmitted by a dominant gene. If that gene is inherited from either parent, the offspring will develop HD. If the gene is NOT inherited, then the offspring will not have HD- AND cannot pass the gene to their offspring.
What is a human genetic disorder caused by a dominant gene is?
One example is Huntington's Disease. Carried on a dominant gene, it causes deterioration of the central nervous system, affecting movement, swallowing, personality, etc.
Autosomal dominant genetic disorder?
An autosomal genetic disorder is Huntington's disease.
How would you know if you had a dominant gene?
You would know if you had a dominant gene if you exhibit the trait associated with that gene. Dominant genes override recessive genes when inherited, so if you have a dominant gene, you will express the associated trait in your physical appearance or characteristics. A dominant gene will be expressed in the presence of a recessive gene.
When a particular inherited characteristic is controlled more by one gene of a pair than by the other the stronger gene is called?
dominant
Osteogenesis imperfecta is dominant or recessive?
Osteogenesis imperfecta is typically inherited in an autosomal dominant pattern, meaning one copy of the mutated gene is enough to cause the condition. However, in some cases, it can be inherited in an autosomal recessive pattern if both parents are carriers of the mutated gene.
What is a trait that is expressed even if only one gene for that form of the trait is inherited?
It is a dominant trait. You only need one gene of a dominant trait for that trait to be expressed. You need two copies of the recessive trait in order for the trait to be expressed.
