If an individual expresses a dominant disease will the children always inherit the disease?

Not always. It depends if the individual is a hybrid- meaning they have both the dominant and the recessive gene. They can pass on the recessive gene instead of the dominant one, and assuming the other parents also passes on the recessive gene, the child will not inherit the disease.

What is caused by a dominant allele that expresses itself late in a persons life?
Huntingtons Disease
Is huntington disease a autosomal dominant disorder?
Yes, Huntington's disease is an autosomal dominant disorder caused by a mutation in the HTT gene on chromosome 4. An affected individual has a 50% chance of passing on the mutated gene to each of their children.
Hurlington disease is an autosomal dominant disorder that affects the nervous system if a man is heterozygous for the alleles that cause the condition and has children with a woman who lacks then?
If a man who is heterozygous for the Hurlington disease alleles has children with a woman who does not have the alleles, there is a 50% chance that each of their children will inherit the disease allele. Since Hurlington disease is autosomal dominant, inheriting just one copy of the disease allele will result in the individual being affected by the disorder.
Will every individual who inherits the allele for Huntington's disease develop the disease?
Yes, Huntington's disease is autosomal dominant with high penetrance. Every individual who inherits the allele gets the disease.
What is it called when you have only one dominant allele to get the disease?
This is known as a dominant genetic disorder, where a person needs to inherit only one copy of the dominant allele in order to express the associated trait or disease.
Is the allele causing huntington's disease dominant or recessive?
Huntington's disease is caused by a dominant allele
Is heart disease dominant or recessive?
It is Dominant.
If you have a genetic disease is it certain that your children will have it?
No. If it is transmitted on a recessive gene, it is possible to be a carrier, but not have the disease. If transmitted on a dominant gene, then the odds of any one child getting the disease are 50-50.
This is caused by a dominant single gene defect and generally does not appear until the individual is 35-45 years of age?
Huntington's Disease.
Huntington's disease is an autosomal dominant disorder that affects the nervous system If a man is heterozygous for the alleles that cause the condition and has children with a woman who lacks?
the man has huntingtons disease
Is Charcot-Marie-Tooth Disease dominant or recessive?
It is Dominant
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.
