A chromatid really only exists during the first two stages of mitosis(prophase and metaphase). This is when the DNA has been replicated and the chromosomes essentially is composed of 2 identical segments.

∙ 15y agoDuring the S phase (synthesis), chromosomes duplicate and can be called sister chromatids. Sister chromatids are exact copies of each other joined together by a centromere. As long as they are joined, they are called sister chromatids and when they are seperated, they are called chromosomes. They do not become visible until Prophase of mitosis or meiosis however. So after the S phase (which comes after G1), the number of chromatids will be twice the n number. During the S phase (synthesis), chromosomes duplicate and can be called sister chromatids.

Oficially we don't know how much foood people eat in a day

How many chromatids have one chromosome?
Two (2). Before DNA replication, each chromosome is composed of a single chromatid. After replication, but before separation of the chromatids during anaphase, this is true.
If the original cell has 8 chromosomes how many chromosomes does the daughter cell have?
It depends on the cell. If the cell is a non sex cell, the daughter cell has 46 chromosomes, if it a human cell. If it is a gamete, it has 23, half the number of the parent cell. This is in a human as well.
How many sister chromatids present during anaphase of mitosis?
A human body cell has 46 chromosomes. Before mitosis, the DNA/chromosomes replicate, resulting in 92 chromosomes which will be divided into two genetically identical daughter cells during mitosis.
How many chromatids are visible at prophase?
It depends on the organisms. In humans there are 46 double chromosome, which are called sister chromatids. There are a total of 92 sister chromatids, which will eventually separate into individual chromosomes during anaphase of mitosis.
How many copies of each chromosome do haploid cells have?
22
How many chromatids does each chromosome have before S-phase?
There are two chromatids for each chromosome before the S-phase. The S-phase is wherein DNA of each chromosome is replicated.
How many chromatids have one chromosome?
Two (2). Before DNA replication, each chromosome is composed of a single chromatid. After replication, but before separation of the chromatids during anaphase, this is true.
How many chromatids would you expect to find in human cells?
There are 46 chromosomes in each body cell, and there are 2 chromatids per chromosome, therefore there are 92 chromatids in each body cell.
How many chromatids are involved in crossing over of a homologous pair of chromosomes?
four two in each chromosome
How many chromatids are in a tetrad?
All tetrads contain four chromatids. Each "leg" is one chromatid.2Tetrad = 2 homologous chromosomes1 homologous chromosome has 2 chromatids joined together by a centromere.That means that there are four chromatids in a tetrad
If a diploid organism has 11 chromosomes how many pairs of sister chromatids does each cell possess?
Assuming it is not in the anaphase stage then the chromosomes had 22 sister chromatids. 1 chromosome has 2 sister chromatids.
A cell containing 92 chromatids at metaphase of mitosis at its completion how many chromosomes will be made?
Each chromatid is a doubled chromosome. At telophase a single chromosome from each chromatid is pulled to its new nucleus, leaving two new nuclei with 46 chromosomes each.
How many sister chromatids are in a bivalent?
A bivalent contains two duplicated homologous chromosomes.
How many chromatids makes up a chromosome when a cell is ready to divide?
the correct answer is 25
How many chromatids are present in a chromosome t the beginning of mitosis?
Two chromatids are present in a chromosome at the beginning of mitosis.
What will happen to an unfertilized egg that undergoes mitosis but not cytokinesis?
Mitosis will separate the sister-chromatids of each chromosome, and each will now be called a chromosome (or daughter-chromosome).Without cytokinesis, the mother-cell will not split into two daughter-cells. The result will be a cell with twice as many chromosomes as the mother-cell.Since an unfertilized egg (ovum) is a gamete, it must be haploid. Doubling the number of chromosomes will produce a diploid cell.
How many chromatids are found in each daughter cell?
It depends on the type of cell. In ordinary somatic (body) cells it is the same as the parent cell. In sex cells it is half the number. Many animals and plants have numbers of chromosomes that are different from human cells numbers.
