What is the nervous system that breakdown that is caused by an autosomal recessive allele?
achondroplasia
Recessive disorder that results from the absence of an enzyme required to break lipids down?
tay-sachs disease
Is Tay-Sach Disease sex-linked dominate or recessive?
Tay-Sachs disease is caused by a genetic mutation in the HEXA gene on (human) chromosome 15. It is is a rare autosomal recessive genetic disorder and not sex-linked.Two Tay-Sachs alleles are required for an individual to exhibit symptoms of the disease.It causes a progressive deterioration of nerve cells and of mental and physical abilities that begins around six months of age and usually results in death by the age of four.
Why is tay sachs is considered recessive level and codominant at the molecular level?
The part of tay sachs that kills you is recessive. Some proteins are still expressed even if you are a heterzygous carrier of tay sachs (less than if you are homozygous recessive but more than homozygous dominant) making the molecular view of tay sachs codominant.
Describe 2 genetic disorders and discuss how they are inherited?
Marfan's syndrome is an autosomal dominant disorder of connective tissues. What is inherited is a defect in the chromosome 15q21, that codes the FBN1 gene. This gene is necessary for proper synthesis if a type of connective tissue called fibrillin. Patients have skeletal abnormalities, eye changes, cardiovascular problems, and a marked tendency to bruise. Tay-Sachs disease is a lysosomal storage disorder, characterised by ganglioside accumulation. This is due to an enzyme deficiency in the lysosome that cannot digest the gangliosides and hence leads to progressive accumulation.
Is tay-sachs caused by codominant alleles?
No, autosomal recessive
Is Tay Sachs dominant or recessive?
It is neither recessive nor dominant because it is a chromosomal disorder and not just a problem present in a single gene.
Is Tay Sachs disease a dominant lethal allele?
I believe it is an autosomal recessive disorder, meaning it is only apparent with a homozygous recessive genotype. But i could be wrong (i loathe biology). oh really?
Is inherited autosomal recessive disorder in which a person lacks the enzyme that is necessary to break down a certain lipid in the brain resulting to brain damage?
Tay Sachs Disease
What is the nervous system that breakdown that is caused by an autosomal recessive allele?
achondroplasia
Recessive disorder that results from the absence of an enzyme required to break lipids down?
tay-sachs disease
What is the most likely explanation for this diagnosis given that infantile Tay-Sachs disease is an autosomal recessive trait?
A distant relative that the mother never met had the disease.
Is Tay-Sachs disease recessive?
Yes. In order to develop Tay-Sachs, you must inherit the gene for it from BOTH parents. If you inherit from ONE parent, you can be a carrier, but will not develop the disease. If BOTH parents are carriers, your odds of inheriting Tay-Sachs is 1-4. Other genetic diseases, such as Huntingtons, are carried on a dominant gene- If one parent has gene, odds are 1-2. Link at the bottom of the page for more information on Tay-Sachs:
Is alzheimer's disease sex linked or autosomal?
Tay-sachs is autosomal.
What are recessive genetic disorder?
When a genetic disorder is recessive, that means that two copies of the gene are necessary to have the trait or disorder. One is inherited from the mother, and one from the father. Disorders of this type include: cystic fibrosis, sickle cell anemia, and Tay-Sachs disease.
Is Tay-Sach Disease sex-linked dominate or recessive?
Tay-Sachs disease is caused by a genetic mutation in the HEXA gene on (human) chromosome 15. It is is a rare autosomal recessive genetic disorder and not sex-linked.Two Tay-Sachs alleles are required for an individual to exhibit symptoms of the disease.It causes a progressive deterioration of nerve cells and of mental and physical abilities that begins around six months of age and usually results in death by the age of four.
Which type of genetic disorder is Tay-sachs?
It is a recessive defect of a gene on chromosome 15. If both parents carry it and the child gets both copies, he will get this degenerative nerve disorder.
