What does 45,XO signify in terms of chromosome composition? Why is this often referred to as Monosomy X in genetics?

Turner syndrome. Monosomy because there is only one functional X chromosome instead of a pair.

1 X chromosome is missing i.e. 45 chromosomes (44 + XO)
Also called as Monosomy X = TURNER SYNDROME

The karyotype shows 45,X, which means there is only one X chromosomes. So,the total number of chromosomes becomes 45 instead of 46.
It is called Monosomy X because one chromosome is missing, leaving only a single X. This condition is commonly seen in Turner syndrome.
This karyotype shows a total of 45 chromosomes instead of the standard 46.
It is Turner syndrome characterized by a 45, X or 45, X0 karyotype, which corresponds to 44 autosomes and only one X chromosome, for a total of 45 chromosomes. One X chromosome is missing from the pair so it is called monosomy X.
This signifies that instead of 46,XX/XY there is only one sex chromosome. This is characteristic of Turner Syndrome, a condition seen in females. It is called Monosomy X because individual has only one X chromosome instead of usual two.
What 45,XO signifies:
45 = Total number of chromosomes, instead of the normal 46.This condition is known as Turner syndrome. It occurs in females and is characterized by short stature, ovarian insufficiency, and other physical features.
Turner’s Syndrome
45,XO - This indicates individual has total 45 chromosomes in each cell.
X - denotes 1 functional chromosome and 0 - denotes absence of other sex chromosome from pair.
Mono means One hence, the term monosomy because only 1 sex chromosome is present
Humans have 46 chromosomes (23 pairs) and the 23rd pair is called sex chromosome which determines the gender of a person. If the 23rd pair has XX chromosomes it means the offspring is a female and if 23rd pair has XY chromosomes it means the offspring is a male.
The image shows the absence of one sex chromosome also referred as Monosomy.
The 45,XO signifies that there are 44 chromosomes (autosomes) and one X chromosome which is 45th chromosome. Thus, denoting Turner Syndrome.
Disease is Turner syndrome because only 45 chromosome present.The sex chromosomes (labeled X and Y) show a significant discrepancy. There is only one X chromosome present, and the Y chromosome is missing entirely (indicated by the arrow pointing to a lone X).Turner syndrome typically affects females and can lead to various medical and developmental issues, such as short stature, failure of the ovaries to develop, and heart defects.
45,XO means a person has only 45 chromosomes with just one X chromosome, and the second sex chromosome is missing. It is called Monosomy X because there is only one X chromosome instead of a pair, which is seen in Turner syndrome.
This is the chromosomal pattern seen in Turner’s syndrome where the last pair is missing making it single also know as monosomy
Turner syndrome!!
45, X-- indicates monosomy X. It means there is only one X chromosome instead of usual two sex chromosome. This condition is commonly associated with turner syndrome.
that’s turner syndome for sure that characterised by monosomy X.
The given chromosome combination denotes the presence of turner syndrome mostly prone to women,due to lack of one X chromosome or its partial presence.
The above karyotype denotes X chromosome monosomy because one X chromosome is missing in the pair (45, OX). That occurs in Turner syndrome.
It’s 45,XO..missing of one X chromosome..
And so it’s x monosomy
MONOSOMY means MONO= single and SOMY= Number of chromosomes
That means one single chromosome of x instead of pair.. it’s name as Turner’s Syndrome
every cell is made up of 46 chromosomes(23pairs), but in Turner syndrome(seen in females), cells show 45 chromosomes + one X chromosome,another X chromosome is missing.
This is Turner’s syndrome where females are characterized by monosomy and are presented with conditions such as infertility, short stature, etc
