23 pairs
Yes animals do sometimes have Turner's syndrome or Klinefelter's syndrome with similar characteristics as those observed in humans.
If you mean how many; there are 46, or 23 homologous pairs. There are 22 autosomal pairs and the sex chromosomes (X and X/Y). This can vary in some disorders, such as Down Syndrome, Turner Syndrome, Klinefelter's Syndrome, and Triple X Syndrome.
There are 46 chromosomes in a normal human cell and 23 in the sex cells. People with down syndrome has 47 chromosomes.
No, it is not possible for identical twins to have different sex chromosome conditions like Turner syndrome and Klinefelter syndrome. Identical twins develop from a single fertilized egg, so they have the same genetic material, including the sex chromosomes. If there was a nondisjunction event in one twin leading to an abnormal number of sex chromosomes, it would affect both twins, not just one.
Yes, Non-disjunction occurs when sex chromosomes fail to separate. This occurrence leads to variable numbers of chromosomes and the manifestation of developmental diseases such as Down syndrome, Turner syndrome, etc.
Turner Syndrome is a genetic disorder that affects females only. It is caused by the absence of all or part of one of the X chromosomes. This condition is not passed down through family genetics, but occurs randomly.
Turner syndrome is the result of one of the two X chromosomes being missing or damaged in some or all cells. These chromosomes are the sex chromosomes, which determine whether a person will be male or female. As people with Turners only have an X chromosome and no Y chromosome they are born female.

not a very bad (effective) symptom
47There 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.

21 chromosomes
Having too many chromosomes, a condition known as aneuploidy, commonly leads to genetic disorders such as Down syndrome (trisomy 21), Edwards syndrome (trisomy 18), and Patau syndrome (trisomy 13). These conditions can result in a range of physical and developmental challenges, impacting an individual's health and well-being.
