If a person has a gene for lets say Diabetes then it will be passed on to the next generation through reproduction. even if a person does not have diabetes but carries the gene for it the next generation might carry on too.
Through genes......
More specifically, the interaction between the parents' dominant and recessive genes provides you with the probability that the offspring will have the disease. That probability changes depending on if the parents actually carry the gene, and whether that gene is dominant or recessive (as the former will increase the likelihood that the child will inherit the disease).
to be correct Down syndrome can not be passed from generation to generation.
It is just at random that a parent has a copy of chromosome 21 and scientist are still working to this day to find a working cure.
Its not, its a sex trait Its not, its a sex trait
Down syndrome cannot be spread from one person to another; it is not contagious. Down syndrome happens when chromosome 21 is present.
Downs syndrome is an example of Aneuploidy in humans. There are 47 chromosomes deployed, an extra at chromosome 21, it is a defect in cell division.
It isn't "passed". Down syndrome is an extra chromosome.

Disorders, such as Down's Syndrome, are caused by nondisjunction.
The exact cause of Tourette syndrome is currently unknown, but it is well established that both genetic and environmental factors are involved. Genetic epidemiology studies have shown that the overwhelming majority of cases of Tourette syndrome are inherited, although the exact mode of inheritance is not yet known and no gene has been identified. It seems unlikely that only a single gene controls Tourette syndrome, most likely it is the result of some suite of interacting genes.
Multiple factor inheritance

There is no mode of inheritance
The mode of inheritance for Turner Syndrome is recessive. Hope I helped, I have to do a project on it anyway!!
In one kind of abnormal chromosome inheritance called Down syndrome, a child has three copies of Chromosome 21!
chromosome 21
The "autosomal dominant" method of inheritance. if your question as Marfan syndrome is the result of inheriting a single allele. Individuals with Marfan syndrome are tall and long-limbed, and have both cardiovascular and eye defects. The inheritance of Marfan syndrome is an example of ______. then the answer is pleiotropy
x-linked dominant inheritance
Pleiotropy.
Pleiotropy.
no
There are lots of ways. A simple way is to do a Punnett Square. It's useful in studying independent inheritance patterns (multiple traits that are not on the same chromosome).
