Chromosomes

Humans have 23 pairs of chromosomes; 46 chromosomes in all, 23 from the father and 23 from the mother.
A normal human being has 23 chromosomes from each parent, giving them 23 pairs or 46 in total. It is called Haploid.

Chromosomes are thread-like structures composed of DNA and proteins found in the nucleus of a cell. They carry genes, which are the units of heredity responsible for determining specific traits. Humans typically have 46 chromosomes organized into 23 pairs.

Chromosome numbers in gametes are always half that of normal cell. For example human cells have 46 chromosomes but a human gamete (sex cell e.g sperm/eggs) will have half that number which in this case will be 23. The number is chromosomes is halfed in gametes so that when the sperm meets the egg and the fuse to make a zygote that you get half the genetic material from your Mother and half from you Father, meaning you are not a clone.

Down syndrome (trisomy 21) is a disorder associated with an error in the number of chromosomes present. Other examples of disorders associated with an error in the number of chromosomes are Trisomy 18 (Edwards Syndrome), Trisomy 13 (Patau Syndrome), Triple X syndrome, and Klinefelter Syndrome.

Autosomes are non-sex chromosomes that are present in both males and females. They determine an individual's traits and characteristics, excluding those related to sex determination.

The two components of chromosomes are DNA and proteins. DNA carries the genetic information that is passed from one generation to the next, while proteins provide structural support and help regulate various cell functions.

Phenylketonuria (PKU) is caused by a mutation in the PAH gene located on chromosome 12. This gene is responsible for producing an enzyme called phenylalanine hydroxylase, which is essential for breaking down the amino acid phenylalanine. Mutations in this gene can lead to the accumulation of phenylalanine in the blood, resulting in the symptoms of PKU.

A human sperm contains 23 chromosomes, half the number of chromosomes found in a normal human cell. During fertilization, the sperm combines with an egg cell, which also contains 23 chromosomes, to form a new cell with a total of 46 chromosomes.

There are 20 chromosomes in a mango, but since it is diploid, in mitosis the number increases to 40, then splits to become two identical cells, each with 20 chromosomes.

No, a hair does not have chromosomes. Chromosomes are found within the cells of an organism and contain the genetic material that determines traits. Hair is composed of a protein called keratin and does not contain genetic material like chromosomes.

Blueberry plants typically have 24 chromosomes.

Mitosis results in two daughter cells, each with the same number of chromosomes as the parent cell. So, in humans, mitosis ends with 46 chromosomes in each daughter cell.

Apes all have 24 pairs, except humans have 23 pairs of chromosomes. It appears that there was a fusion of chromosome #2 in humans. The genomes are still good matches otherwise and the differing number of chromosomes do not effect the consensus that humans and other apes have a common ancestor. http://www.youtube.com/watch?v=Gs1zeWWIm5M&fmt=18

Humans typically have 46 chromosomes in each cell, with 23 pairs inherited from each parent. These chromosomes contain genes that carry genetic information and determine traits such as hair color, eye color, and height.

Chromosomes have no direction in how they assort other than that they align in homologous pairs. The individual genes are part of the chromosomes and go wherever the chromosome goes just like the motors of cars go wherever the car goes.

Homologous chromosomes are a set of chromosome pairs, one set maternal and the other paternal, that pair up during meiosis, the production of reproductive cells. The pairs have the same genes in the same locations, though once spread out the different pairs segregate out. the biggest way that these chromosomes change up is by exchanging lengths of the material.

same traits
the same traits as each other. Different chromosome pairs code for different traits than other chromosome pairs do though. Only homologous chromosomes (chromosome pairs) code for the same trait as each other.

Animals typically have a specific number of chromosomes characteristic of their species. For example, humans have 46 chromosomes (23 pairs) in most of their cells. Chromosomes contain genetic material, including DNA, which carries the instructions for an organism's development and functions.

No. The human X chromosome contains over 1000 genes, many of which are essential for life. The Y chromosome in comparison has only about 120 genes. A zygote with Y0 or YY (one or two Y chromosomes) would not be viable.

A duplication of the chromosomes is what must happen before meiosis can begin.

Bivalents or Tetrad of homologous chromosomes consisting of four synapsed chromatids that become visible during the Pachytene stage of meiotic prophase

or

A four-part structure that forms during the prophase of meiosis and consists of two homologous chromosomes, each composed of two sister chromatids.

The usual number of chromosomes in a baby's cell ( zygote ) is 46 . 23 chromosomes from both the male's reproductive cell ( sperm ) and the female's reproductive cell ( egg ) .

A chromosome aberration is a structural anomaly in an individual's chromosomes, such as deletions, duplications, inversions, or translocations. These aberrations can lead to genetic disorders or abnormalities in the individual's development and physiology. Detection of chromosome aberrations is an important aspect of genetic testing and diagnosis.

Yes, the cytoskeleton helps to organize and separate chromosomes during cell division. It forms the mitotic spindle, which is responsible for guiding and segregating chromosomes to opposite poles of the cell during mitosis.

Chromosomes are copied during the S phase of the cell cycle, which occurs prior to cell division. This process is known as DNA replication, where each chromosome is duplicated to ensure that the daughter cells receive a complete set of genetic information.
