What is the designation for the short arm of a chromosome?
Chromosome # + p
so the short arm of Chromosome 11 is referred to as 11p
Clustering is a process of putting similar data into groups. This
paper presents data clustering using improved genetic algorithm
(IGA) in which an efficient method of crossover and mutation are
implemented. Further it is hybridized with the popular Nelder-
Mead (NM) Simplex search and K-means to exploit the
potentiality of both in the hybridized algorithm. The performance
of hybrid approach is evaluated with few data clustering
problems. Further a Variable Length IGA is proposed which
optimally finds the clusters of benchmark image datasets and the
performance is compared with K-means and GCUK[12].The
results revealed are very encouraging with IGA and its
hybridization with other algorithms

Which is the largest chromosome?
If you consider the haploid human genome occupies a total of just over 3 billion DNA base pairs, and the genome is stored on 23 chromosome pairs.
3,000,000,000 / 23 = 130,000,000 (rounded to nearest hundred thousand).
So one gene is roughly one-hundred-million base pairs.
What happens to chromosomes after mitosis?
After mitosis, the sister chromatids that make up each chromosome separate and are divided into two new daughter cells. Each daughter cell receives a complete set of chromosomes identical to the original cell.
What is the difference between DNA and chromosome?
DNA contains the genetic instructions for a living cell's function. Chromosomes are thread-like structures that contain DNA and histone proteins.
A chromosome is a loosely defined term, and vary widely among different organisms.
DNA is a set of instructions, and chromosomes help fit the DNA molecules into a cell's nucleus. Chromosomes are essential units for cellular division and replication to insure genetic diversity.
How many chromosomes do bullfrogs have?
100000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
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).
What does the seventh chromosome do?
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.
What is a Chromosome complement?
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?
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.
What are the sister chromatids in a chromosome attached by?
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.
If the liver cell of an animal have 24 chromosomes how many chromosomes do its sperm cells have?
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.
A gene on the female chromosome having no allelic partner on the y chromosome would be what?
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
How many chromosomes does a human with monosomy have?
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.
What chromosomes are autosomes?
The 44 chromosomes that are not sex chromosomes. 1st through the 22nd pair. The X and Y chromosomes are the only chromosomes not autosomes.
Are chromosomes found in the nucleus?
no,
DNA
Cytoplasm
and Nucleolus are the only things found in the nucleus
What is the purpose of chromosomes?
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.
What causes the deletion of chromosome 5?
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.
What is a chromosomal mutation?
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.
What causes a chromosome inversion?
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.
How many pairs of chromosomes do females have?
In humans, the somatic cells of both females and males have 23 chromosome pairs.
What is the chromosome number?
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.
