Chromatids are not identical because they undergo genetic recombination during meiosis, where segments of DNA are exchanged between homologous chromosomes. This process introduces genetic variation, leading to chromatids with different combinations of alleles. Additionally, mutations can also occur during DNA replication, further contributing to differences between chromatids.

The two identical portions that are attached by their centromere are known as?
The two identical portions that are attached by their centromere are known as sister chromatids. They are produced during DNA replication and are separated during cell division.
Why do chromosomes have 2 sister chromatids?
they're identical because they are the product of replication.
Are sister chromatids identical before crossing over occurs?
Yes they are attached at the centromere and remain identicle until crossing over occurs in prophase 1 of meosis
What is the function of chromatids?
Chromatids are the two identical copies of DNA that make up a replicated chromosome. They are joined at the centromere and separate during cell division, ensuring each daughter cell receives an identical set of genetic information.
In what stage do chromatids separate?
Chromatids separate during the anaphase stage of mitosis. This is when sister chromatids are pulled to opposite poles of the cell by the spindle fibers, leading to the formation of two identical daughter chromosomes.
What two identical bodies make up a duplicated chromosome?
Somatic cell chromosome is made of two identical chromatids
Are sister chromatids identical?
they're identical because they are the product of replication.
What object holds chromatids together during mitosis?
The centromere. It where the two identical sister chromatids come closest in contact.
The two identical portions that are attached by their centromere are known as?
The two identical portions that are attached by their centromere are known as sister chromatids. They are produced during DNA replication and are separated during cell division.
Are the two sister chromatids that are connected by a centromere identical to one another?
Yes, sister chromatids are identical because they are produced through DNA replication. They are held together at the centromere before being separated during cell division.
Before cell division begins each chromosomes consists of two identical joined chromosomes called?
Before cell division begins, each chromosome consists of two identical joined chromatids called sister chromatids. Each sister chromatid contains an identical copy of the chromosome's DNA molecule.
What could cause the sister chromatids in metaphase 1 not to be identical?

Why do chromosomes have 2 sister chromatids?
they're identical because they are the product of replication.
How do sister chromatids differ from homologous chromosomes?
Sister chromatids are identical while homologous chromosomes are merely similar.They are different because they separate the cells and then they become babies but only the homologous chromosomes do.
Are sister chromatids identical before crossing over occurs?
Yes they are attached at the centromere and remain identicle until crossing over occurs in prophase 1 of meosis
During the cell cycle when would a chromosome consist of two identical sister chromatids?
A chromosome consists of two identical sister chromatids during the S phase of the cell cycle when DNA replication occurs. This ensures that each daughter cell receives an identical copy of the genetic material during cell division.
When a double helix DNA is replicated two complete helices are formed together these helices are called sister?
chromatids. They are identical copies of the original DNA molecule.
