What types of Down syndrome are there?
There are three different types of Down syndrome: Standard Trisomy 21, Translocation, and Mosaicism. Standard Trisomy 21 is when the extra chromosome 21 comes from either the egg or sperm cell. Between 90% and 95% of all Down syndrome is Standard Trisomy 21.
Who carries the cri du chat defective chromosome?
Individuals with Cri du Chat syndrome carry a deletion on the short arm of chromosome 5, specifically the region known as 5p15.2. This deletion leads to developmental and intellectual disabilities as well as characteristic facial features associated with the syndrome.
How do you know if you have turrets?
The best way to know if you have Tourette's is to get tested. Tourette's comes in many forms. You should see a doctor.
What are the stages of Down syndrome?
There are three different kinds of Down syndrome: Translocation, Trisomy 21, and Mosaic.Translation: occurs when a piece of chromosome breaks off and attaches to another.Trisomy 21 (the most common kind): caused by meiotic disjunction, or in other words a gamete produces an extra of Chromosome 21.Mosaic is similar to Trisomy 21 in that it still has the extra chromosome in the cell, but also some of the other cells in the body have a normal amount of chromosomes.

Why do geneticists suspect that the extra chromosome seen in down syndrome usually comes from the egg rather than the sperm?
Geneticists suspect that the extra chromosome seen in Down syndrome usually comes from the egg rather than the sperm because women are born with all the eggs they will ever have, and the risk of an error during egg development increases with maternal age. Sperm, on the other hand, are constantly being produced, so the likelihood of an error leading to an extra chromosome is lower.
Is non disjunction the only cause of down syndrome?
No.There are three different types of Down syndrome: Standard Trisomy 21, Translocation, and Mosaicism. Standard Trisomy 21 is when the extra chromosome 21 comes from either the egg or sperm cell. Between 90% and 95% of all Down syndrome is Standard Trisomy 21.
Can you give a sentence for chromosome?
The genetic difference between men and women comes down to the X and Y chromosome
What can be done to treat down syndrome?
You can not treat the syndrome itself, only the physical complications that comes with it.
Dangerous as it may be what chemical's ability to mess with your dopamine and glutamate levels may mean it has medical uses when it comes to Parkinson's Tourette's and Alzheimer's?
The chemical you are referring to is likely methamphetamine. While it can be dangerous due to its potential for addiction and serious side effects, methamphetamine's ability to affect dopaminergic and glutamatergic systems may have potential therapeutic applications in treating Parkinson's disease, Tourette's syndrome, and Alzheimer's disease. Research is ongoing to explore its potential benefits in these conditions.
Where does each chromosome in a pair of homologous chromosomes come from?
Each chromosome in a pair of homologous chromosomes is inherited from one parent. One chromosome comes from the mother (maternal) and the other from the father (paternal).
