or maybe 3.

human male is having 27 chromosome x2 now. out of this one pair contains the sex determining genes. they are of two types Xand Y. male have XX and female have XY.

Chromatin are a network of irregular,thin,thread-like fibres present in the nucleoplasm of the nucleus. When the cell division occurs, then these fibres(irregular) change to chromosomes(with a definite shape like that of an open scissors).

The seventh chromosome carries genetic information that determines various traits and characteristics in a person, such as physical appearance, metabolism, and immune system function. It is also involved in the regulation of many genes that control key cellular functions throughout the body.

A chromosome complement refers to the total number and types of chromosomes present in an individual's cells. It is specific to each species and can vary among different organisms. This complement plays a crucial role in determining an individual's genetic makeup and characteristics.

Threadlike coils of chromosomes are called chromatin, which is composed of DNA and associated proteins. Chromatin undergoes further condensation during cell division to form distinct chromosomes. The chromosomes contain the genetic material necessary for cell functions and are essential for the accurate transmission of genetic information to daughter cells.

There are 13 pairs of homologous chromosomes in a primary spermatocyte, which means there are 26 chromosomes. During meiosis, the primary spermatocyte undergoes two divisions, resulting in four spermatids with 13 chromosomes each. Therefore, a sperm cell would also have 13 chromosomes.

Sister chromatids in a chromosome are attached by a structure called the centromere. The centromere is a region where the two sister chromatids are held together until they separate during cell division.

Body cells, like liver cells, are diploid. This means they have pairs of chromosomes. In this example the diploid number of chromosomes is 24. In sperm cells (or egg cells) the number of chromosomes is halved. This is described as the haploidnumber. In this example the haploid number would be 24/2 = 12. So the number of chromosomes in the sperm cells would be 12.

An individual (male) with an allele on the X chromosome but no corresponding allele on the Y chromosome is described as hemizygous. Genes which are inherited in this way are described as sex-linked or X-linked. An example is hemophilia - the inability of the blood to clot. It is caused by a recessive allele, so males only need to inherit one copy to develop the characteristic. Females can inherit one hemophilia allele and one normal allele, so they can act as carriers of the disease without developing it themselves. See http://en.wikipedia.org/wiki/X-linked_gene

A human with monosomy has 45 chromosomes instead of the usual 46. This genetic condition results from the loss of one chromosome in a pair, leading to various health issues depending on which chromosome is affected.

In human beings there are 23 pairs of chromosomes.Out of those,22 pairs are common for both male and female.But the 23rd pair of chromosome is different for both.It is the sex chromosome.It determines the sex of a person.In the 23rd pair,the chromosomes are X&X for females and X&Y for males.If the father releases X chromosome,then a girl child is formed and if he releases Y chromosome,then a boy child is formed.

There are cases in humans of XXY men (Klinefelter's syndrome), XYY men (XYY syndrome) and XXX and X women.

The 44 chromosomes that are not sex chromosomes. 1st through the 22nd pair. The X and Y chromosomes are the only chromosomes not autosomes.

and Nucleolus are the only things found in the nucleus

Chromosomes contain DNA, which carries genetic information that determines an organism's traits. During cell division, chromosomes ensure that each daughter cell receives the correct amount of genetic material. Additionally, chromosomes play a role in gene regulation and gene expression.

Deletion of chromosome 5 can be caused by genetics mutations during cell division, exposure to certain chemicals or radiation, or spontaneous errors in DNA replication. It can also be inherited from a parent who carries a chromosomal abnormality.

A chromosomal mutation is a change in the structure or number of a chromosome. This can involve rearrangements, deletions, duplications, or inversions of genetic material within a chromosome. These mutations can lead to genetic disorders or affect an individual's development and health.

Chromosome inversions are caused by breaks in the chromosome followed by rejoining in an inverted orientation. This can happen due to errors during cell division or exposure to mutagens. Inversions can also be inherited from parents.

In humans, the somatic cells of both females and males have 23 chromosome pairs.

The original cell (before meiosis occurs) will have a chromosome number of 2n.

After meiosis, the resulting daughter cells will have a chromosome number of n.

So the daughter cells will have half the number of chromosomes as the original cell.

For example, a normal somatic (non-sex) human cell will have 46 chromosomes.

Each gamete (the result of meiosis) will therefore have 23 chromosomes.

The human cell has 46 chromosomes. In the sex cell of a human it has one half that many. So 23 chromosomes from each parent. Different species have different number of chromosomes. This is why you do not have mixes such as a centaur.

Chromosomes are structures within cells that contain DNA molecules. DNA is the genetic material that contains the instructions for building and functioning of organisms. Each chromosome is made up of a long strand of DNA wrapped around proteins that help organize and compact the DNA.

Chromosomes are duplicated during the S phase of the cell cycle, which occurs during interphase. This is when DNA replication takes place to ensure that each daughter cell receives a complete set of chromosomes during cell division.

A chromosome is an organized structure of DNA and protein that is found in cells. A chromosome is a single piece of DNA that contains many genes, regulatory elements and other nucleotide sequences. Chromosomes also contain DNA-bound proteins, which serve to package the DNA and control its functions
