Telomere .

During meiosis, chromosome exchange occurs at the chiasmata, which are points of crossing over between non-sister chromatids. The exchange involves the exchange of genetic material between homologous chromosomes, not specifically at the centromere or telomere regions.

Is chromosome Y an acrocentric chromosome?
A chromosome is determined to be metacentric, acrocentric or telocentric by the location of its centromere. Centromeres are the point of attachment of two sister chromatids. Sister chromatids are formed during DNA replication prior to mitosis or meiosis. Chromosome Y by itself (when it is not replicating and there are no sister chromatids) is not acrocentric, as it wouldn't even have a centromere location.
Which phase of mitosis does the centromere divide chromatids split and identical chromosome move to opposite ends of the cell?
metaphase I of meiosis
How does the significance of meiosis maintained the chromosome number?
No. Meiosis results in halving of chromosome number. Chromosome number after one round of meiosis is half that of original chromosome number. Generally, meiosis takes place during gamete formation. So when two gametes fuse, they lead to restoration of the chromosome number. Hence chromosome number can be maintained in sexually reproducing organisms.
What phase is when each chromosome is connected to a spindle fiber?
During metaphase each chromosome attaches to spindle fibers. The centriole anchors the spindle fibers and helps in splitting the chromosome.
What is the difference between a chromatid and a centromere?
The centromere is the region of the chromosome that holds the two sister chromatids together during mitosis. The chromatid is one of the two strands of chromosomes that become visible during mitosis or meiosis.
What is the function of centromere?
the centromere keeps the two sister chromatids together. its also where the chromosome attaches to the spindle apparatus during mitosis and meiosis.
What happens during metaphase in meiosis?
chromosomes move to the middle of the cell. mitotic spindles from the centrioles attach to the centromere of the chromosome

Chromosome Y by itself (when it is not replicating and there are no sister chromatids) is not acrocentric, as it wouldn't even have a centromere location.
What will happen to chromosomes that has two centromere?
centromere is place at which spindle fibers are attached if the centromere is lost then chromosome will lose its point for the attachement of the spindle fiber and then will not be able to take part in mitosis. chromosome is usually lost in this case.
Which phase of mitosis does the centromere divide chromatids split and identical chromosome move to opposite ends of the cell?
metaphase I of meiosis
What holds chromosomes together?
The centromere holds chromosomes together. It is the circle like thing in the middle of the chromosome.

Are the chromosome copied before meiosis or during meiosis?
before
Experiments with cohesion have found that?
cohesions are protected from cleavage at the centromere during meiosis I.
What phase is when each chromosome is connected to a spindle fiber?
During metaphase each chromosome attaches to spindle fibers. The centriole anchors the spindle fibers and helps in splitting the chromosome.
After meiosis I each daughter cell contains Please explain why one chromosome of each homolog is incorrect I added my reasoning to the answer this question?
Homologous chromosomes (also called homologs or homologues) are chromosome pairs of approximately the same length, centromere position, staining pattern, with genes for the same characteristics at corresponding loci. In meiosis I, the chromosomes are duplicated first then the homologous pairs separate together. Sections of the DNA can sometimes cross over between homologous pairs. Later, during Meiosis II, these pairs are separated into the gametes with only one of each pair. If you said there was only one chromosome, you are thinking of the final result of meiosis.
What is a chromosome repository in meiosis?
polar body
