The chromatids are attached to each other at the Centromere. Hope that helps have a nice day.

If an organism has 16 chromosomes in each of its egg cells what is the diploid number?
EACH CHROMOSOME WILL PRODUCE ONE DUPLICATE CROMATID FOR ITSELF AND THE TWO CHROMATIDS WILL GET ATTACHED TO EACH OTHER THROUGH THE CENTROMERE.SO AFTER DUPLICATOIN 16 SISTER CHROMATIDS WILL BE PRESENT BUT TOTALLY(16 ORIGINAL CHROMATIDS + 16 DUPLICATED CHROMATIDS) 32 CHROMATIDS WILL BE PRESENT
Are sister chromatids or homologous chromosomes more similar?
Sister chromatids are replicated DNA and are identical. Homologous chromosomes are not, as one comes from the mother and the other comes from the father.
Which phase of meiosis do sister chromatids pull apart and move to opposite ends of the cell?
Sister chromatids are pulled apart from each other during the anaphase II stage of meiosis II. From there the chromatids are taken to opposite poles of the cell and create two haploid cells.
Are sister chromatids identical?
they're identical because they are the product of replication.
The phase of mitosis during which chromosomes become visible and the centrioles separate from one another is?
Prophase. The chromosomes become more conspicuous because they gradually condense during prophase. The centrioles separate in animal cells; plant cells lack centrioles.
When all the genes of a chromosome have duplicated but are still attached the strutures that are formed are called?
When all the genes of a chromosome have duplicated but are still attached, the structures that are formed are called sister chromatids. Sister chromatids are identical copies of each other, and they are held together at a specialized region called the centromere.
Where is the region where the identical DNA molecules are most tightly attached to each other?
After DNA replication, when each chromosome exists as a pair of identical sister chromatids, the sister chromatids are tightly attached to each other at the centromere.
The point at which two chromatids are attached to each other in a chromosome is called?
Centromere!
What are segments of nonsister chromatids that break and reattach to the other chromatid?
sister chromatids
Why is it pointless for sister chromatids to crossover?
Crossing-over occurs between non-sister chromatids, since (prior to crossing-over) sister chromatids are genetically identical (i.e. one is a duplication of the other). Therefore, if sister chromatids underwent a cross-over, no genetic variation would occur.

How many chromatids does each chromosome have after S-phase?
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.
What is the area where a pair of chromatids is attached is the?
The Centromere, use the wiki article for further reading.
What is the difference between a chromatid and a sister chromatid?
Homologous chromosomes is a pair made of a paternal and maternal chromosomes. But sister chromatid is either pairs of paternal or maternal chromosomes
Are sister chromatids or homologous chromosomes more similar?
Sister chromatids are replicated DNA and are identical. Homologous chromosomes are not, as one comes from the mother and the other comes from the father.
What structure is formed by two sister chromatids being held together by a centromere?
A bivalent.Sister chromatids are normally joined at the centromere. When homologous chromosomes pair, the two sister chromatids of one chromosome join with the two sister chromatids of the other chromosome. So it is really the joining of non-sister chromatids that is special.The word "bivalent" refers to the temporary combining of the two chromosomes (four chromatids). The bivalent forms in prophase I of meiosis, and is split in anaphase I.
What is the small section of a chromosome where sister chromatids attach to each other?
Centromere
