Chromosome is having more than one X gene. Having more than one X chromosome cause Down syndrome.

∙ 6y agoA chromosome is a threadlike strand of DNA in the cell nucleus that carries the genes in a linear order. It is also known as tightly wound DNA. It is a structure that DNA wraps around.
MORE INFORMATION:
A chromosome is an organized structure of DNA and protein that is found in cells. It is a single piece of coiled DNA containing many genes, regulatory elements and other nucleotide sequences. Chromosomes also contain DNA-bound proteins, which serve to package the DNA and control its functions.
Chromosomes vary widely between different organisms. The DNA molecule may be circular or linear, and can be composed of 10,000 to 1,000,000,000 nucleotides in a long chain.
Cells may contain more than one type of chromosome; for example, mitochondria in most eukaryotes and chloroplasts in plants have their own small chromosomes.
Chromosomes are the essential unit for cellular division and must be replicated, divided, and passed successfully to their daughter cells so as to ensure the genetic diversity and survival of their progeny.
Chromosomal recombination plays a vital role in genetic diversity. If these structures are manipulated incorrectly, through processes known as chromosomal instability and translocation, the cell may undergo mitotic catastrophe and die, or it may aberrantly evade apoptosis leading to the progression of cancer.
In practice "chromosome" is a rather loosely defined term. In prokaryotes and viruses, the term genophore is more appropriate when no chromatin is present. However, a large body of work uses the term chromosome regardless of chromatin content. The simplest genophores are found in viruses: these DNA or RNA molecules are short linear or circular genophores that often lack structural proteins.
Chromosomal DNA encodes most or all of an organism's genetic information; some species also contain plasmids or other extrachromosomal genetic elements.

A strand of DNA
A chromosome is a long, thread-like structure made of DNA and proteins that carries genetic information. It is found in the nucleus of a cell and contains the instructions needed for an organism to develop, grow, and function. Humans typically have 46 chromosomes arranged in 23 pairs.

What is the designation for the short arm of a chromosome?
The short arm of a chromosome is denoted as "p" in chromosome nomenclature. For example, if a chromosome is labeled as 15p, it means that it is chromosome 15 with the short arm indicated.
Is the smallest gene cell chromosome?
Chromosome 21 is the smallest human chromosome. Inside of the chromosome, there are 48 billion nucleotides, the building blocks of DNA.
What various types of genetic material in order from simplest to most complex?
nucleus → chromosome → gene
What chromosomes can be affected by changes in chromosome numbers?
Any chromosome can be affected by changes in chromosome numbers. This can include trisomy (three copies of a chromosome), monosomy (one copy of a chromosome), or other abnormalities such as deletions or duplications. These changes can lead to genetic disorders or abnormalities.
What is a sat chromosome?
A sat chromosome, short for satellite chromosome, is a chromosome with a secondary constriction that contains highly repetitive DNA sequences called satellite DNA. These regions appear as small, secondary appendages on the chromosome and play a role in chromosome structure and organization.
Is an x chromosome and chromosome the same thing?
An x chromosome is specifically a feminine chromosome. With a x and y chromosome its male, with a x and x, it is a female.
Which chromosome contains the sex gene?
chromosome 1 chromosome 1
What is the designation for the short arm of a chromosome?
The short arm of a chromosome is denoted as "p" in chromosome nomenclature. For example, if a chromosome is labeled as 15p, it means that it is chromosome 15 with the short arm indicated.
Does an x chromosome looks the same as a y chromosome?
No. An 'X' chromosome looks like an 'X'. The 'Y' chromosome looks like a deformed 'X'. It is noticeably different to an 'X' chromosome. Also, the 'Y' chromosome is only a third of the size of an 'X' chromosome - an 'X' chromosome is 155 million base pares, while the 'Y' chromosome is only 58 million base pairs.
4 chromosome mutations?
Deletion: Part of a chromosome is missing. Duplication: A segment of a chromosome is copied multiple times. Inversion: A segment of a chromosome is reversed in orientation. Translocation: Part of a chromosome breaks off and attaches to another chromosome.
What is the difference between Edward's syndrome and Patau's syndrome?
in Patau there is an extra chromosome in chromosome 13, in Edwars it the extra chromosome is in chromosome 18
What condition is carried on a chromosome other then the sex chromosome?
The gene that causes cystic fibrosis is located on chromosome 7, which is an autosome, not a sex chromosome.
List these in order from smallest to largest chromosome gene cell?
Smallest to largest: Gene (a place on a chromosome); chromosome (there are 46 in human cells); and DNA (because it accounts for all the genetic material in a cell).
What sex chromosome is present in all humans?
There are two sex chromosomes: the X chromosome and the Y chromosome. During fertilization, the mother always gives an X chromosome and the father gives either another X chromosome or a Y chromosome. Therefore, all humans have at least one X chromosome.
What chromosome is associated with Downs?
Chromosome 21.
Is a chromosome a allele?
No, a chromosome is a structure that contains genetic information, while an allele is a specific variant of a gene located on a chromosome. Chromosomes contain many alleles that determine an individual's traits and characteristics.
What chromosome does hemophilia come from?
The X Chromosome.
