Is Nail-patella syndrome hereditary?
Nail-patella syndrome (NPS), also known as hereditary osteo-onychodysplasia (HOOD), is a rare, genetically determined disease, which is inherited as a dominant trait. So yes, it is hereditary.
Is nail patella syndrome recessive?
No, it is not recessive. Nail-patella syndrome is inherited in an autosomal dominant manner. This means that possession of only one copy of the defective gene is enough to cause disease. When a parent has nail-patella syndrome each of their children has a 50% chance to inherit the disease-causing mutation. A new mutation causing nail-patella syndrome can also occur, causing disease in a person with no family history. This is called a sporadic occurrence and accounts for approximately 20% of cases of nail-patella syndrome. The children of a person with sporadic nail-patella syndrome are also at a 50% risk of developing signs of the disorder.
What chromosome is nail patella syndrome found on?
Nail Patella Syndrome is found on chromosome #9. If you search "what chromosome is nail patella syndrome on?" in Google, then it will give you a bunch of websites that have a bunch of info. about it. hope this helps. :-)
How common is nail patella syndrome?
The population is as far as 1 in 50,000 people suffer from yellow nail disease but the same is increasing and has reached to the limit of 1 per 30,000.
What is a dominate trait?
Dominant trait is a genetics term. A dominant trait is one which will be expressed if one of the parents has the gene for that trait. A recessive trait is one that will be expressed only if both parents carry the trait.
What type of trait prevents the other type from being seen?
A recessive trait. When a recessive allele is with a dominant allele, only the dominanate trait can be seen.
A living thing that shows a dominant trait may be homozygous dominant or homozygous recessive for the trait true or false?
False because a living thing that shows a dominant trait can not be homozygous recessive. If it is homozygous recessive it will show recessive trait. A living thing that shows dominant trait may be homozygous dominant or hetrozygous.
What is a trait that masks a trait called?
A trait that masks another trait is called a dominant trait. This means that when an organism carries both dominant and recessive alleles for a particular gene, only the dominant trait will be expressed in the phenotype.
The form of a trait that appears to mask another form the same trait is called what?
The form of a trait that appears to mask another form of the same trait is called the dominant trait. Dominant traits will be expressed over recessive traits in a heterozygous individual.
A trait that appears or is expressed in the f1 generation is what?
A trait that appears or is expressed in the F1 generation is considered dominant. Dominant traits will manifest themselves in the offspring when at least one parent carries the dominant allele for that trait.
What is an observable trait of an organism that can mask a recessive trait?
The observable characteristic are called the genotype and any dominant trait can mask the recessive. An example would be Black Angus cattle can actually carry a red recessive trait because black is the dominant trait in cattle breeding
What does it mean that an organism is homozygous dominant for a trait?
Homozygous Dominant for a trait means that an organism has two dominant alleles for that trait. Here's an example: Trait: Widow's Peak Widow's Peak allele: Dominant (D) No widow's peak allele: Reccessive(d) Homozygous Dominant (DD) Homozygous Reccessive (dd) Heterozygous (Dd)
