A karyotype will consist of all the homologous pairs of chromosomes and also one pair of chromosomes representing the sex of the organism (male/female). In Humans, a karyotype will consist of 22 homologous pairs of chromosomes and 1 pair of either XX or XY chromosomes. The total number of homologous pairs of chromosomes depends largely upon which organism is being taken into account, since each organism has its characteristic number of chromosomes in a diploid cell - in humans this is 46.

How many chromosomes are usually found in a karyotype?
There are a total of 4 rows in a karyotype chart.
How should a human karyotype look like?
A human karyotype typically consists of 22 pairs of autosomes and one pair of sex chromosomes (XX for females, XY for males), totaling 46 chromosomes. The chromosomes should be arranged in size order, with the sex chromosomes typically shown separately. Abnormalities in chromosome number or structure can lead to genetic disorders.
Where are sex chromosomes found?
The sex chromosomes will usually be in the last place on the karyotype (typically the bottom right corner). If/when the karyotype is numbered, the sex chromosomes should be numbered as the 23rd pair.
How many chromosomes should a zygote have so the baby's body cell will each have a normal set of chromosomes?
A zygote should have 46 chromosomes: 23 from the egg and 23 from the sperm. This will ensure that after fertilization, the baby's body cells will each have a normal set of 46 chromosomes.
A cell in the stem tip of a corn plants contions 20 chromosomes After this cell divides how many chromosomes should each resulting daughter cell contain?
Each resulting daughter cell should also contain 20 chromosomes. During the cell division process known as mitosis, the cell's chromosomes are duplicated and then divided equally between the two daughter cells.

How the karyotypes of klinefelter syndrome differ from the normal karyotypes?
The karyotype of a person with Down Syndrome differs from a normal karyotype because it contains a three chromosomes in the 21st slot, where there should only be a pair of two. That is why this is called Trisomy 21.
If the body cells of humans contain 46 chromosomes a single sperm cell should have?
A primary spermatocyte with 46 chromosomes will undergo meiosis and yield four spermatids with 23 chromosomes. A primary spermatocyte undergoes meiosis I two haploid secondary spermatocytes are produced.

What would happen if a new formed cell had 46 chromosomes?
If it is a human (somatic/non-sex) cell, it should function as normal because this is the correct number of chromosomes.
If a sex cell has eight chromosomes how many chromosomes will there be after fertilization?
in a normal human cell there are 46 chromosomes but sex cells only have half these (23) because when the female sex cell and the male sex cell come together and fertilise they add up to 46 (making a human cell which will multiply into a baby human) In your questions state you are only using 8 so a normal cell would have double that (16) to make a baby of that species of animal or plant ect.
How can a genetic disorders as Turner syndrome occur?
Going down to the cellular level, it occurs in meiosis when chromosomes fail to separate (nondisjuction). We get a set of chromosomes from our paternal side and the other set from out maternal side. For example, one of the gamete that may have came from our maternal side contains no chromosomes , O, when it should contain that chromosome x while from our paternal side we get a gamete containing the x chromosomes. This results in a XO, a sterile female when the normal sex chromosomes are XX or XY. -or- nondisjunction
Why should there be a normal number of chromosomes?
because if there isn't 46 in a human they can have medical problems like down syndrom
Can a sperm cell contain maternal chromosomes?
Absolutely (assuming you are referering to the maternal chromosomes of the man who is making the sperm) , the human set of chromosomes is composed of 46 pairs with half (23) coming from each parent. Mendel's laws suggest that each chromosome segregates and separates independently during mitosis (and subsequently meiosis) thus each gamete should contain a mixture of paternally and maternally derived chromosomes.
