Barr Bodies In Klinefelter Syndrome

Men with Klinefelter syndrome have a Barr bodies in their nuclei the same as 46XX females. Klinefelter syndrome KS is a genetic disorder in which the testes the male gonads do not produce their principle hormone testosterone. In mammals sex is determined by two sex chromosomes known as the X and the Y chromosomes. The analysis of chromosomes in 64 cases showed a karyotype of 47XXY in 59 cases a 46 XY47XXY mosaic in 4 cases and 46XX46XY47XXY mosaic in 1 case. It can affect physical and mental development. Klinefelter syndrome is a condition that occurs in men as a result of an extra X chromosome. The Barr body diagram indicated below.

For example there would be two Barr bodies in a cell from an XXX female or XXXY male.

Like females XXY males with Klinefelter syndrome will convert one X to a Barr body in each cell. The number of BBs per cell is 1 less than the number of X chromosomes thus normal XX women cells will have one BB as do men with 47 XXY Klinefelter syndrome. They do have fertility problems because there are two active X chromosome in their testes and this interferes with spermatogenesis. Of individuals with Klinefelter syndrome. Genes located on either the X or the Y chromosome are known as sex-linked genes. Even when an additional X chromosome is added such as Klinefelter syndrome in males Barr body will still be less than X chromosomes.

Barr bodies in klinefelter syndrome. Nearly half of all men with Klinefelter syndrome develop metabolic syndrome which is a group of conditions that include type 2 diabetes high blood pressure hypertension increased belly fat high levels of fats lipids such as cholesterol and triglycerides in the blood. Humans have 46 chromosomes which contain all of a persons genes and DNA. Indicate the expected number of Barr bodies in interphase cells.

Triple X females as well as Klinefelter males with more than two X chromosomes neutralize their extra Xs by forming additional Barr bodies. Klinefelter syndrome also known as XXY syndrome is a condition in boys and men thats caused by an extra X chromosome. Genes located on either the X or the Y chromosome are known as sex-linked genes.

In mammals sex is determined by two sex chromosomes known as the X and the Y chromosomes. Of individuals with Klinefelter syndrome. The Barr body diagram indicated below.

Barr body A condensed clump of chromatin that corresponds to an inactivated X chromosome which is located next to the nuclear membrane and best seen in somatic cells in interphase. Klinefelter syndrome KS is a genetic disorder in which the testes the male gonads do not produce their principle hormone testosterone. Klinefelter syndrome is a condition that occurs in men as a result of an extra X chromosome.

The number of BBs per cell is 1 less than the number of X chromosomes thus normal XX women cells will have one BB as do men with 47 XXY Klinefelter syndrome. It can affect physical and mental development. Adults with Klinefelter syndrome may also have primary hypogonadism decreased testosterone production small andor undescendent testes cryptorchidism enlarged breast tissue gynecomastia tall stature andor inability to have biological children infertility as well as an abnormal opening of the penis hypospadias and an small penis micropenis.

Genes on any chromosomes other. Sex-Chromatin was found positive in 62 of 64 cases of Klinefelters syndrome verified by chromosome analysis. For example there would be two Barr bodies in a cell from an XXX female or XXXY male.

Like females XXY males with Klinefelter syndrome will convert one X to a Barr body in each cell. The Genetics of Calico Cats.

Nearly half of all men with Klinefelter syndrome develop metabolic syndrome which is a group of conditions that include type 2 diabetes high blood pressure hypertension increased belly fat high levels of fats lipids such as cholesterol and triglycerides in the blood. The number of Barr-bodies ranged from 1-45 200 cells evaluated x mean was 96. Men with Klinefelter syndrome have a Barr bodies in their nuclei the same as 46XX females.

They make enough sperm to conceive children using intracytoplasmic sperm injection though.
