Does your karyotype represent a male of a female?
chromosome, known as the sex chromosomes, that determines whether the person is male or female. Females have two Xs and males have one X and one Y. Since the above figure shows two X chromosomes, this karyotype is from a typical female. However, you will rarely see such a picture for your child.
How do you determine a karyotype?
To observe a karyotype, cells are collected from a blood or tissue sample and stimulated to begin dividing; the chromosomes are arrested in metaphase, preserved in a fixative and applied to a slide where they are stained with a dye to visualize the distinct banding patterns of each chromosome pair.
What determines male or female?
A child's biological sex (male or female) is determined by the chromosome that the male parent contributes. Males have XY sex chromosomes while females have XX sex chromosomes; the male can contribute the X or Y chromosome, while the female must contribute one of their X chromosomes.

A person's biological sex is determined by the sex chromosomes: females have two X chromosomes, or XX; most males have one X chromosome and one Y chromosome, or XY. Males with XXY syndrome are born with cells that have an extra X chromosome, or XXY.
What is a karyotype in genetics?
A karyotype test looks at the size, shape, and number of your chromosomes. Chromosomes are the parts of your cells that contain your genes. Genes are parts of DNA passed down from your mother and father. They carry information that determines your unique traits, such as height and eye color.

A normal male karyotype- 46,XY. The Y chromosome is a unique identity for males. In comparison to other chromosomes, the Y chromosomes have fewer genes. An important gene for maleness that is the SRY is located on the Y chromosome. The SRY gene is located on the TDS region on the short arm of the Y chromosome.
What is the condition where X and Y are present?
For example, with X and Y sometimes another X chromosome also occurs, the condition is known as Klinefelter syndrome: 46, XXY. Here the present on two X chromosomes causes infertility, intellectual disabilities, and developmental problems. Although the condition occurs totally randomly.
What are the common chromosomal abnormalities?
Common chromosomal abnormalities are translocations, duplications, deletions, insertions, and inversions. Besides, a change in the number of chromosomes is also one of them.
How is a super female developed?
The super female is developed by the presence of one extra X chromosome in a pair due to the event called nondisjunction. Notably, no serious health-related issues are associated with it. Sometimes a large duplication of X chromosome results in X-linked acrogigantism.
Why do we use female karyotypes?
Female karyotypes are used to identify chromosomal aberrations in females. Similar to male karyotyping, female karyotyping is done for the growing fetus, to confirm the gender and identify chromosomal defects in females at the early development stages of the life.
What are the two stains used to identify chromosomes in male and female karyotypes
Stains used to identify chromosomes in male and female karyotypes are Giemsa and Quinacrine. The main purpose of a male or female karyotype is to identify the sex of an individual and to determine defects in chromosomes. Defects in male or female karyotypes result in physiological and clinical manifestations.
What is the 23rd chromosome?
The male karyotype testing is done to identify the chromosomal aberrations present in males which is characterized by the 23rd chromosome pair consisting of an X and a Y chromosome and the female karyotypes reveal information on chromosomal aberrations of females which is characterized by the 23rd chromosome pair having two X chromosomes in it.
What is a karyotype?
Karyotype is a technique performed for genetic analysis and is defined as an image of an individual’s collection of chromosomes. There are two types of karyotype; the male and female karyotypes. Karyotyping of a genome is done to identify the defects in chromosomes which are referred to as chromosomal aberrations. In Karyotype testing, a wide snapshot of the individual’s chromosomes is taken in order to observe the pairing and ordering of chromosomes. Karyotypes are prepared using standardized staining procedures. The most common stain used in karyotyping is Giemsa. The field of chromosome analysis is known as Cytogenetics, and these chromosomal pictures reveal information about important genetic diseases such as Down’s syndrome, Klinefelter’s syndrome, and different ploidy conditions, etc.
Why do we do karyotyping?
The karyotyping test is done for the growing fetus to confirm the gender of the fetus. And also to identify chromosomal defects in males at an early development stages of life. Karyotypes are prepared from chromosomes extracted from a specific cell during the meta phase or the prometaphase.
What is the most common stain used in karyotyping?
The most common stain used in karyotyping is Giemsa. The field of chromosome analysis is known as Cytogenetics, and these chromosomal pictures reveal information about important genetic diseases such as Down’s syndrome, Klinefelter’s syndrome, and different ploidy conditions, etc. Karyotypes can be mainly of two types.
How to develop a karyotype?
The process of developing a karyotype involved basic steps including cell culturing, propagation, staining and observation. The procedure begins with the short-term culture of cells derived from a specimen, which is most often a blood cell sample. The cells are then allowed to grow in a particular media, and the resulting cells are harvested. The cells are arrested in the metaphase. This is done by addition of colchicine, which poisons the mitotic spindle. The cell nuclei are allowed to swell and burst using a hypotonic solution. The nuclei are then treated with a chemical fixative, dropped on a glass slide, and treated with various stains such as Giemsa. The chromosomal structures are then revealed via microscope observations.
What is the difference between male and female karyotypes?
The male karyotype refers to the appearance of the complete set of chromosomes in a somatic cell of a male while the female karyotype refers to the appearance of the complete set of chromosomes in a somatic cell of a female.
What are the characteristics of a male karyotype?
However, the main characteristic feature of a male karyotype is the presence of an X chromosome and a Y chromosome in the sex chromosome pair. In other words, the Y chromosome is one of the two sex-determining chromosomes in humans as well as many other species. It only passes from father to the son.
