XO
A karyotype is a picture of the chromosomes in a cell. For example, a human cell has 46 chromosomes. In the karyotype, 23 pairs of chromosomes will be shown (23 x 2 = 46). A karyotype can show different types of mutations, depending on which chromosome it affects. For example, Down Syndrome is a trisomy in chromosome 21, so there will be THREE instead of two chromosome 21s. You can research more mutations shown by chromosomes in a karyotype.
The karyotype of an XO human would be deficient one X chromosome, compared to that of a normal female, and it would result in a female. Normal human females only use one X chromosome, whereby one is inactivated, which is why an XO human is viable. An XXY human would have one extra X chromosome as compared to that of a normal male, and it would result in a male. Again, an X chromosome is inactivated, which is why an XXY human is viable. XO is referred to as Turner Syndrome. XXY is referred to as Klinefelter Syndrome.
The question is not really clear. A karyotype is the overall complement of chromosomes isolated from a cell or organism (eukaryotic). When the karyotype of a normal healthy female is prepared for viewing by a cytogeneticist, there are 22 pairs of autosomal chromosomes present (ie two of chromosome 1, two of chromosome 2 etc...). There is one additional pair of sex chromosomes (two copies of X). A normal healthy human male also has 22 pairs of autosomes but the pair of sex chromosomes is not matched but instead there is one X chromosome and one Y chromosome (which is smaller than the X). So, if you look at a karyotype that has been laid out - if the two sex chromosomes are different sizes (X and Y) then the karyotype is from a male, if however they are the same size (X and X) then the karyotype is from a female.
A karyotype is defined as the chromosomes of a cell. The human karyotype has one pair of sex chromosomes and 22 pairs of autosomal chromosomes.
when the chromosomes is 47 or less than 46
I believe the answer to your question is 23.

There are 46 chromosomes in a human Karyotype.
The karyotype of the asexual organism would not contain homologous chromosomes
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.
