Explain the simultaneous origin of Turner Syndrome and color blindness by the abnormal behavior of chromosomes at meiosis?

Meiotic non-disjunction is used to describe abnormal behavior of sex chromosomes during meiosis although the cause may be non-conjunction or failure of pairing rather than failure of separation of chromosomes or chromatids.
The child only has one X chromosome. So the mother must be X+X- and the father is just X+Y. So the child is X- , with the X- from the mom and nothing from dad.
B.
Yes it can. Non-disjunction n-1 gamete fertilized an egg from mom with the mutant X chromosome. She has the mutant allele from her mother and the non-disjunction came from her father because of the n-1 rule.
C.
You cannot distinguish whether the abnormal chromosome behavior occurred at the first or second division of meiosis. The reason for this is because with non-disjunction meiosis both parts give you the n-1 rule. So, you cannot tell if it occurred during meiosis I or meiosis II.

An abnormal condition that a person inherits through genes or chromosomes is a?
An abnormal condition that a person inherits through the chromosomes or genes is a genetic disorder.
What will happen if sex cells carry diploid chromosomes?
It will result 4n cells.Chromosomal number will be doubled from generation to generation. It also will result in abnormal individuals that may not to be able to adapt. Down's Syndrome and Turner's Syndrome are examples of this.
Why might Cells from an advanced malignant tumor most often have very abnormal chromosomes and often an abnormal total number of chromosomes?
Chromosomally abnormal cells can still go through cell cycle checkpoints.
What if you have 47 chromosomes?
the child will be abnormal..
What conditions can aneuploidy of sex chromosomes cause?
An example of aneuploid condition is Down syndrome, is due to three copies of choromosome 21 or trisomy 21.
Why a person with Down's syndrome has an abnormal number of chromosomes?
Yes.
Does a mongoloid baby be cure?
I think you are referring to Down's syndrome. It is due to abnormal number of chromosomes in the cells There is no cure.

On what chromosomes can you find the genetic disorder called Down Syndrome?
Trisomy 21 is the scientific name for the cause of Down Syndrome. Triplication of the 21st chromosome occurs giving it 3 chromosomes total. This is caused when disjunction (splitting) of the chromosome during meiosis does not occur and leaves one cell with 22 chromosomes and the other with 24. When a cell with an abnormal # of chromosomes (24) merges with one having the normal # (23), the resulting fertilized egg has (3) 21st chromosomes or a total of 47.
What is one example of an abnormal number of chromosomes in humans?
An untenable offspring; the death of your fetus.
What gene is affected by Barth syndrome?
Barth syndrome occurs when a person is born with a mutated, or abnormal, TAZ1 (or G4.5) gene. This abnormal gene is located on the X chromosome, which is a sex-determining chromosome. Males have one X and one Y chromosome, while females have two X chromosomes.
What is the medical term meaning condition in which a person has an abnormal number of chromosomes?
The general term is aneuploidy. Some examples: Down Syndrome is a commonly known condition in which the person has an extra copy, making three, of the 21st chromosome. Others are Edwards Syndrome (an extra 18th) and Patau Syndrome (and extra 13th).
