How many barr bodies are present in a normal xx female?
A normal XX female will typically have one Barr body, which represents the inactivated X chromosome. The other X chromosome is active, while the inactive X chromosome condenses into a Barr body during development to compensate for gene dosage between males and females.
An individual with Turner syndrome appears male and has 1 Barr body?
A person with Turner syndrome typically has female characteristics, but may have some physical features mirroring male traits, such as a broad chest or a low hairline. The presence of one Barr body in their cells is normal, as individuals with Turner syndrome have a single X chromosome.
Does a human female carry two Barr bodies?
Sex in humans is determined by the combination of sex chromosomes, X and Y. In males, every cell in their body (except for erythrocytes (red blood cells, which are non-nucleated and do not contain DNA)) and sperm cells (which only contain either a single X or Y chromosome) contains both X and Y chromosomes. In females, every cell (except those previously mentioned in males) contains two X chromosomes, except that one of those (through a process believed to be random) X chromosomes atrophies into what is called a "Barr body". Basically, this is a transcriptionally inactive chromosome (in that there is no gene expression from this chromosome). Only 1 of the 2 X chromosomes in each cell undergoes this. Your question is worded strangely because it sounds like you're asking if the ENTIRE female body contains 2 Barr bodies, when in fact it contains billions and billions of bar bodies...however, I suspect you were asking on the cellular level, and thus every somatic (non-sex) cell in the female body contains a single Barr body and a single functional X chromosome.* *There are genetic anomalies that may be the exception to this, but this is in normal, healthy females.
A Barr body is normally found in the nucleus of which kind of human cell?
A Barr body is normally found in the nucleus of female human cells. It is an inactivated X chromosome, which compensates for the presence of two X chromosomes in females by silencing one of them to achieve dosage compensation.
Where can barr bodies be found?
BARR BODIES CAN BE SEEN AS A SMALL APPENDAGE ON THE NUCLEOUS OF A POLYMORPHONUCLEAR NEUTROPHIL OF BLOOD CELLS FROM A FEMALE HUMAN. THESE ARE ONE OF THE WHITE CELL TYPES SEEN ON A BLOOD SMEAR DONE ON A CBC. tim goodman clinical lab scientist
