the 21 chromosome group has 3 chromosomes rather than twogiving the child 47 total chromosome rather than 46.
Down syndrome is caused by a genetic abnormality in Chromosome 21. It is highly unlikely that X-Ray exposure causes genetic abnormalities such as this. However, X-Rays are not recommended while pregnant.
Down syndrome is a genetic abnormality caused by the presence of an extra copy of chromosome 21. People with Down syndrome often have characteristic facial features, cognitive impairment, and may also have physical abnormalities, such as heart valve disease.
Common autosomal chromosomal abnormalities include Down syndrome (trisomy 21), Edwards syndrome (trisomy 18), Patau syndrome (trisomy 13), and Turner syndrome (monosomy X). These abnormalities result from errors in chromosome number, leading to characteristic physical and developmental features. Diagnosis is often made through genetic testing such as karyotyping or chromosomal microarray analysis.
A karyotype of an individual's white blood cells can be used to diagnose chromosomal abnormalities such as Down syndrome, Turner syndrome, and Klinefelter syndrome. It can also detect genetic disorders caused by aneuploidy or large structural chromosomal changes.

Chromosomal disorders are caused by abnormalities in the chromosomes.
A karyotype shows the number, size, and shape of chromosomes in a cell. It allows for the identification of genetic abnormalities and can be used to diagnose chromosomal disorders such as Down syndrome.
Yes
There's many different genetic disorders such as: Down Syndrom Canavan Disease Muenke Syndrome Bloom Syndrome etc
The genetic developmental defect is spelled "Down Syndrome" or sometimes "Down's Syndrome."
