How does the cell adjust to the extra X chromosome in female cells?
In females, the extra X chromosome becomes inactive and becomes the Barr body.
What does a Barr body in a mammalian female cell represents?
A Barr body is an inactivated X chromosome in mammalian female cells, primarily serving to balance gene expression between males and females who have one active X chromosome. This process is known as Lyonization, which equalizes the dosage of X-linked genes in males (XY) and females (XX).
What sex chromosomes are contained in a female body cell?
Female cells contain the sex chromosomes XX. A female gamete (ovum/egg) contains one X chromosome.
Is barr body found in 80 percent polymorphonuclear leucocytes?
The Barr body is a condensed, inactive X chromosome typically found in female cells. It is not typically found in polymorphonuclear leukocytes but rather in cells where X chromosome inactivation has occurred, such as in female somatic cells. The presence of a Barr body does not specifically relate to polymorphonuclear leukocytes.
How is the haploid chromosome number?
The haploid chromosome number is half the chromosome number of the body cells. For example, in humans, body cells have 46 chromosomes. In human haploid cells (sex cells), there are 23 chromosomes.
How do cells become a full human body?

How many pairs of chromosome are there in spinach body cell?
Spinach (Spinacia oleracea) has a diploid chromosome number of 18, which means it has 9 pairs of chromosomes in its body cells. Each pair consists of one chromosome inherited from each parent. This chromosomal arrangement is typical for many plants and plays a crucial role in genetic variation and reproduction.
What is diffrnet from boys DNA and girls DNA?
This varies by species but in humans the female gender has cells with two x chromosomes of which one is randomly inactivated. This inactivated chromosome is referred to as the barr body. The male gender has cells with both an x chromosome and a small y chromosome. Source - Any recent biology textbook.
How many chromosome's do human body cells contain?
21
How many chromosome do normal human body cells have?
5
Why x-chromosome are also called Barr body?
That is what random X chromosomes do in the female somatic cells. They form Barr bodies. This is a methylated X chromosome that effectively shuts this chromosome down, one per cell in a random manner. This is done by the body because too much protein product is detrimental to organisms.
Why do female and male sex cells have fewer chromosomes than the body cells?
The Y chromosome is found in males only. Females have XX chromosomes whereas males have XY chromosomes. That is why they are different, because an XY cannot be female and an XX cannot be male.
