What are the name of 23 chromosomes in human body?

No, there are 46 chromosomes in one cell. A gamete, or sex cell, has 23 chromosomes because during fertilization, the female and male gametes (egg and sperm, respectively) come together to form a new cell with 46 chromosomes


What are the names of all the 46 chromosomes?

The word that describes similar chromosomes, one from each parent is homologous. Each human for example has, with certain exceptions 23 chromosome pairs. Twenty two are called autosomal meaning having basically to do with the body. These pairs are homologous. The remaining are the sex chromosomes, X and Y. Homologous chromosomes have the potential to contain exactly the same genes, but nature has made sure that they don't.


What is a complete list of nucleotide sequence in a individuals chromosome?

It is not possible to provide a complete list of nucleotide sequences on an individual's chromosome in a single answer, as each chromosome contains millions of nucleotides. The human genome has over 3 billion base pairs, which make up the DNA on 23 pairs of chromosomes. The sequence can vary between individuals due to genetic variations.


Is Edwards syndrome autosomal or sex-linked?

Down Syndrome is a trisomy of the 21st chromosome as opposed to an allelic inheritance through the X chromosome. Trisomy is a somatic disorder caused by improper division during gametogenesis (usually of the ovum) that results in 3 copies of the 21st chromosome in the egg once it is fertilized.


How many chromosomes are present in the abnormal karyotype?

In a regular human body cell, there are 46 chromosomes, 23 from each parent. Of these, 2 are sex chromosomes, so named because they determine the sex of the individual. The other 44 (22 in each set) are called autosomes. Any exceptions to the above are instances of aneuploidy. They are relatively rare.

Are all sex genes in male and female located on the sex chromosome?

No, the sex chromosome will just activate them, for instance, masculine characteristics may be on chromosome 3, the y chromosome will activate these in a man and a second x chromosome will deactivate these in a woman.

Describe how the chromosomes pairs are numbered?

It all begins from mitosis. Mitosis is the process of the cell division. Mitosis starts when the chromatin within the cell begins to rearrange into orderly strand called chromosomes. The chromosomes then move into pairs. After that, the chromosome pairs begin to pull apart from each other. Eventually, the chromosome pairs split apart into two new cells with the same makeupas the original cell.

Are klinefelter syndrome and Turner syndrome results of nondisjunction of autosomes?

No, Klinefelter syndrome and Turner syndrome are the result of nondisjunction of sex chromosomes. Klinefelter syndrome is caused by an extra X chromosome (XXY), while Turner syndrome is due to a missing X chromosome (XO).


How many copies of Chromosome 21 are there in someone who has Down syndrome?

3 Pairs of Chromosome 21There are 47 chromosomes in someone with Down syndrome (most people have 46); the 21st pair has an extra chromosome. Down syndrome is also known as "Trisomy 21" - a reference to the fact that someone with Down syndrome has 3 pairs of chromosomes 21.


What sex chromosomes do girls have?

the combination of sex chromosomes for a female is XXX it is the triple x because in 1947 a women in North Bonerville Africa found that women have 3 sex chromosomes while males only have two


What is the sex of the person whose chromosomes are shown in Figure 8-3 above?

It is male because there is an X and a Y chromosome in the table.

What happens when a fetus has 3 cromizones instead of 2?

a "normal" human being should have a total of 46 chromosomes. 23 from mom, 23 from dad. if something goes wrong during meiosis, the chromosomes may not be separated normally and a gamete (sex cell, known as sperm or egg) will have either too few or too many chromosomes. this is known as aneuploidy. the effects of aneuploidy on the zygote will vary depending on what chromosomes you are talking about. in the case of chromosome #21, having one extra is called "trisomy 21" which leads to the condition known as down syndrome. chromosome pairs 1-22 are a person's autosomes. the 23rd pair are sex chromosomes. aneuploidy affecting the sex chromosomes can have various effects, depending on what chromosomes are inherited. as you can see, the effects of aneuploidy depend on the specific chromosome number/pair. aneuploidy usually is not fatal.


What occurs if a cell that is about to divide?

Mitosis (or meiosis in sex cells) occurs. The cell should have already made duplicates of its chromosome, mitosis is basically the alignment and splitting up of these homologous pairs, creating 2 cells with the same number of chromosome. Mitosis is broken down into 4 phases: 1.Prophase 2.Metaphase 3.Anaphase 4.Telophase Look these up if you want to know the specifics of each phase.
