What is the karyotype for a normal human female?
A normal female karyotype would be described as 46 XX. A karotype shows the pairs of metaphase chromosomes of an individual cell and sorted according to size.
How many chromosomes should a normal karyotype contain?
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.
Is a karyotype a type of gene?
No. A karyotype is an arrangement of the 22 pairs of homologous chromosomes and the 2 sex chromosomes according to their size and shape. The chromosomes are photographed during metaphase of mitosis and then arranged by a trained technologist. Karyotypes are determined in order to check for chromosomal abnormalities. Refer to the related links to see examples of a karyotype for a female and one for a male.
How many chromosomes are in karyotype?
A karyotype will show the number of chromosomes in a diploid cell, so there will be 46 chromosomes all together. You get 23 chromosomes from your father and 23 from your mother. Chromosomes are placed together into groups of two known as homologous pairs. The pairs are made up of one chromosome from your father and one from your mother. So, there are 23 homologous pairs. Of the 23 pairs, 22 of them (or 44 chromosomes) are known as autosomes, and they determine various genes of your body based on the pairing. The other two chromosomes are the sex chromosomes. The pair can either be XX (which indicates a girl) or XY (a boy). The mother always gives an X chromosome, it is the father who will determine whether it is a boy or girl by giving an X or Y.
Chromosomes other than X and Y?
Chromosomes that are not X or Y are called homologous chromosomes and autosomal chromosomes. The first 22 pairs of human chromosomes are autosomal.
How many autosomes are present in a normal human karyotype?
There are 46 chromosomes in a human Karyotype.
What is human karyotype?
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.
What best describes Human Karyotype?
Human karyotype = 1 pair of sex determining chromosomes, either xx or xy, and 22 pairs of autosomes.
What best describes the human karyotype?
Human karyotype = 1 pair of sex determining chromosomes, either xx or xy, and 22 pairs of autosomes.
Which pairs on the human karyotype are known as sex chromosomes?
All the chromosomes except the sex chromosomes.
What is the karyotype for a normal human female?
A normal female karyotype would be described as 46 XX. A karotype shows the pairs of metaphase chromosomes of an individual cell and sorted according to size.
What describes the humanities?

Does your karyotype represent a male of a female?
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.
What are the chromosomes in each numbered group of a human karyotype called?
Chromosomes 1-22 are called autosomes.
