Well Down syndrome is causes by the 21st chromosome of a sex cell doubling, and so once fertilisation with the egg commences there will be 3 21st chromosomes. When you have 45 their is multiple things that can happen, the only consistent one is Turner Syndrome, which basically stunts puberty. This only happens in females and it is when they have X instead of XX.

What are the risk of having 45 chromosomes?
a person can only have 45 chromosomes if one of them was translocated to another one. its called a partial monosomy. the person would have a karyotype beginning similar to this if it was a female 45,xx,der. 45 stands for the chromosomes. xx stands for female. and der stands for translocated or rearrangement.
Why is karyotype called 45xo?
This particular karyotype has 45 chromosomes (instead of the usual 46). "XO" tells us that the karyotype is missing a sex chromosome: the individual has an X, but no homologous sex chromosome (X or Y) to complete the diploid pair.
Is 45 x the only known human live born monosomy?
No, 45,X is not the only known human live born monosomy. Other examples include 45,Y (Turner syndrome) and 45,X/46,XX (mixed gonadal dysgenesis). These conditions result from abnormalities in the number of sex chromosomes carried by an individual.
What term describes an organism that only has a single set of chromosomes?
The organism is called abnormal. It only has 45 chromosomes and is a female. She has Turner syndrome, meaning no secondary sex characteristics will form. Also, the female is born sterile and can have no children. Her body will not develop curves and will stay like that of a child. However, this problem (the curves) can be solved with some prescribed hormones.
How many chromosomes does a human with monosomy have?
A human with monosomy has 45 chromosomes instead of the usual 46. This genetic condition results from the loss of one chromosome in a pair, leading to various health issues depending on which chromosome is affected.

What genes or chromosomes is the muitation that causes turners syndrome?
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.
Is 45 x the only known human live born monosomy?
No, 45,X is not the only known human live born monosomy. Other examples include 45,Y (Turner syndrome) and 45,X/46,XX (mixed gonadal dysgenesis). These conditions result from abnormalities in the number of sex chromosomes carried by an individual.

What syndromes is chracterized by karyotype with 45 chromosomes?
Turner syndrome is characterized by a karyotype with 45 chromosomes, including a single X chromosome (X0). This syndrome is associated with short stature, webbed neck, and infertility in individuals with female characteristics.
How many chromosomes in a human karyotype?
A karyotype is the number and appearance of chromosomes in the nucleus of a eukaryote cell. There are 46 chromosomes in a human karyotype. However, there are twenty-three pairs. In a karyotype, chromosomes are showed in pairs, because twenty-three are from one parent, and twenty-three are from another. In a cell, there are twenty-two pairs of chromosomes called autosomes, and one pair of sex chromosomes. The sex chromosomes are different in a male and a female. For a male, it is one x chromosome and one y chromosome. In a female, it is two x chromosomes. So, as a recap, there are 46 chromosomes. The only exceptions to this are autistic people. For them, there is usually a duplication or deletion of one chromosome. In other words, a person would have 47 or 45 chromosomes.
Can a person with 45 or 48 chromosomes survive?
Someone with 45 chromosomes can survive if the missing chromosome is a sex chromosome. 48 chromosomes would be 2 trisomies...if one was a trisomy of chromosome 21 and the other trisomy involved one of the sex chromosomes this would probably produce a living offspring. Other trisomies tend to have more negative effects and it is unlikely that multiple trisomic individuals would survive.
