Would you like to merge this question into it?

Would you like to make it the primary and merge this question into it?

exists and is an alternate of .

One of the suppositions as to why iron might be harmful is based on the fact that people with Down syndrome have an excess amount of superoxide dismutase (SOD) in their cells, due to the extra 21st chromosome.

How does someone get down syndrome?

One doesn't "get" Down's Syndrome, it is a genetic anomaly. Predominantly, the older the mother, the more likely her child will develop Downs. Such children have similar features, such as ears too low, and tend to be clumsy and intellectually challanged. They also tend to be outwardly happy, and ver (MORE)

How many chromosomes are there in someone who has Down syndrome?

47 There are 47 chromosomes in someone with Down syndrome; the 21st pair has an extra chromosome. Most people have 46 chromosomes. Down syndrome is also known as "Trisomy 21" - a reference to the fact that someone with Down syndrome has 3 pairs of chromosomes on their 21st pair.

Causes Down Syndrome?

Having an extra copy of chromosome 21. You are supposed to have 2; when you have 3 (trisomy 21), Down's Syndrome is the result.

How does someone with Down syndrome get that extra chromosome?

During meiosis homologous chromosomes are separated and only one copy of each chromosome goes into the gamete. If they aren't separated correctly, both copies may go into the gamete. After fertilisation, the embryo will contain 3 copies of that chromosome. If this occurs with chromosome 21, it will (MORE)

What causes Patau syndrome and how does it differ from Down syndrome?

\n. \nPatau syndrome is a very rare syndrome caused by a problem in the chromosomes, the structures in the body's cells that contain DNA. The specific chromosomal problem in Patau syndrome is that the cells have three copies of chromosome 13, as opposed to the usual two copies in most people. Becau (MORE)

What is Down Syndrome caused by?

What is the cause of Down Syndrome during meiosis?

Down's Syndrome is caused due to the presence of an extra 21st chromosome, resulting in 3 sets of 21st chromosome instead of just 2. This is because during Anaphase II of Meiosis II non-disjunction occurs and instead of one 21st chromosome going into each gamete, both go into one of the gametes and (MORE)

Causes of down syndrome?

The cause of Down syndrome is one of three types of abnormal cell division involving chromosome 21.

Down Syndrome is a genetically-transmitted disease cause by the presence of part or all of an extra 21st chromosome. We can't blame this one on the drugs. However, drug use (incoluding alcohol) while pregnant could complicate the issue with developmental problems. I always remind people that if t (MORE)

Down syndrome is most commonly caused by?

Downs syndrome is caused by a genetic mutation called trisomy. Trisomy is when an extra chromosome is present on one set of chromosomes, so instead of the 46 chromosomes of a normal human there are 47.
