Down syndrome is neither dominant nor recessive.
It is "autosomal" or "other"; it is simply an error in the translation process of Chromosome 21 (three copies instead of two). Instead of 46 chromosomes, a person with Down syndrome will have 47.

∙ 12y agoDiabetes is neither a dominant or recessive disorder its whats known as a polygenic or 'complex' disease and is caused by the contribution of many different genes working together and signals from the environment around your cells such as nutrition or obesity.
No single gene alone causes diabetes but reason diabetes can be seen to be inherited in families is because in these familes there are a high number of risk alleles (different versions of the same gene) being passed on and these alleles cause a higher risk of developing diabetes.
An example of a gene which causes higher risk of diabetes is DBQ1 which encodes a protein present on the cells surface that works with the immune system to prevent the destruction of insulin producing cells in the body. If a person has two copies of the mutant version of the gene they have an 18 times greater risk of developing diabetes than a person who has two unmutated copies of this gene varient.
But this is just a greater risk of developing the disease it does not mean that a person who has these mutant genes will get diabetes.
Diabetes is a very complex disorder and many tens if not hundreds of genes work together to cause it.

∙ 14y agoDiabetes is the name given to a group of disorders with common symptoms. All involve disturbance to our ability to process glucose.
Some of these disorders have 'loose genetic connections' that reflect primarily a recessive inheritance pattern.
A number can also be shown to have maternal inheritance, suggestive of mitochondrial inheritance.
Yet others express a silent mutation in one of the four genes involved in insulin release when there is overload demand for insulin. These often express as 'mature-onset' or 'Insulin-independent' diabetes.
Finally there is considerable evidence to support the infection theory of diabetes induction, particularly in cases of 'juvenile', also known as 'Insulin-dependent' diabetes. There may be genetic factors responsible for the auto-immune response that triggers the destruction of the pancreas (which tissue produces insulin).
Not surprisingly, you can also acquire insulin-dependent diabetes if you lose your pancreas surgically, either during the removal of a tumor or during attempts to repair damage following a car accident or sporting injury.

∙ 14y agoDiabetes is not a gene but a disease.
While it is speculated that type one diabetes may have a genetic cause to it, scientists are unsure if it is caused by a dominant or recessive gene.

∙ 10y agoDown syndrome is a mutation that takes place during cell division which results in an extra chromosome. It you want to know if the likely-hood of getting down syndrome is dominate or recessive you're asking the wrong question.

∙ 16y agothe allele that causes diabetes is a recessive trait

∙ 8y agois diabetes a dominant or recessive trait? well it is a ressive because it is not that comen in people unless there famly has a history of this disorder.
Wiki User
∙ 12y agonot necessarily everybody is different some people have it and some people don't it isn't something that is passed on with every member of your family. :)

Is diabetes dominant or recessive trait?
It is a recessive trait
In a hybrid individual the trait that is covered and not expressed is the what trait?
recessive
Trait of an organism that can be masked by the dominant by the dominant form of a trait?
A trait that masks another trait is called dominant, or a dominant trait.
When does a recessive trait dominant over a dominant trait?
When two recessive genes are inherited, and the portion of recessive inheritance is 51% or greater in favor of the recessive trait.
A living thing with a dominant and recessive gene for a trait?
A living thing with a dominant and a recessive gene for a trait is heterozygous. This individual will display the dominant phenotype for that trait but may have offspring that display the recessive trait.
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 difference between a dominant trait and a recessive trait?
A recessive trait is a trait that is not shown or expressed physically but is retained within the persons genes, whereas a dominant trait is a trait which opresses the recessive trait and is prodominantly shown or expressed physically. For example it is possible for two red-haired parents, both with recessive dark haired genes, to have a dark haired child. they must both have the recessive gene or the dominant gene of red - hair will be expressed in the child
What a recessive trait?
A recessive trait is a trait that is not dominant, and is not really seen in ones phenotype.
Not expressed when the dominant form of a trait is present?
The recessive trait isn't present when the dominant form of the trait is there. Whenever a trait is dominant trait is present it ALWAYS takes over the recessive one. the law of Dominance
Is glaucoma a dominant or recessive trait?
dominant
Is ADHD a dominant or recessive trait?
dominant
If an offspring receives a pair of trait-controllers containing both a dominant and a recessive trait what happens to the recessive trait?
The dominant trait is shown in that organism with the possibility of carrying either the dominant or recessive gene to the next generation
