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
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?
if an indivigual has a dominent allele for a disease he/she is an affected individual.
How do dominant lethal alleles persist in populations even though their fitness is essentially zero?
Huntington's disease, where the lethal allele expresses itself very late in an individuals life. Persons carrying the dominant lethal allele does not become aware of the disease until after their reproductive age. Thus, they pass the lethal allele to their children without knowing and the allele persists.
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
Is huntingtons disease a autosomal ressesive trait?
Huntington's Disease is an Autosomal Dominant Trait, meaning that only one parent needs to pass the disease for the offspring to inherit it.
