What category of genetic disorder is huntingtons disease?
Autosomal Dominant
What is caused by a dominant allele that expresses itself late in a persons life?
Huntingtons Disease
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.
Autosomal dominant genetic disorder?
An autosomal genetic disorder is Huntington's disease.
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.
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.
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
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 Sex-linked?
No, it is autosomal dominant.
Compare the inheritance of Huntingtons disease with the inheritance of sickle cell anemia?
Huntingtons disease is Autosomal dominant, i.e. a 50% chance of inheritance if one parent has the gene. Where as sickle cell anemia is autosomal recessive. This gives a 25% chance of inheritance if both parents are carriers.
Symptoms of huntingtons disease?
The symptoms of Huntingtons Disease are, mental deterioration and uncontrollable movements; symptoms usually appear in middle ages.
Is huntingtons disease monosomy or trisomy?
Monosomy
