When there is crossing over, then non-sister chromatids of homologous chromosomes cross and twist at the chiasmata, where genetic materials are exchanged. At each if the chiasmata, the chromatids may break and rejoin with another sister chromatid and hence 'crossing over'. So basically, the 'ends' chromatids of the chromosome cross each other, then the chromatids are torn apart from each other.

What happens to each pair of duplicated homologous chromosomes during meiosis 1?
pairing of homologous chromosomes and recombination of genetic material takes place
How is the process of crossing over and independent assortment alike?
The crossing over is the process of exchange of DNA between homologous chromosomes whereas the independent assortment is the process in which the chromosome pairs align themeselves at the equator of the cell . Crossing over takes place in Prophase I of meiosis I whereas the independent assortment takes place in metaphase I of meiosis I.
What is the exchange of a corresponding segment between homologous chromosomes?
The exchange of a corresponding segment between homologous chromosomes is known as genetic recombination or crossing over. This process occurs during meiosis and results in the exchange of genetic material, contributing to genetic diversity among offspring.

When does crossing over take place between homologous chromosomes during meiosis?
Crossing over between homologous chromosomes occurs during prophase I of meiosis.

The exchange of a corresponding segment between homologous chromosomes is known as genetic recombination or crossing over. This process occurs during meiosis and results in the exchange of genetic material, contributing to genetic diversity among offspring.
Why crossing over takes place?
Occurs during prophase I of meiosis (pachytene) in a process called synapsis. Crossover usually occurs when matching regions on matchingchromosomes break and then reconnect to the other chromosome. The value of crossing over is that each parent has a different daughter cell.
Which phrase of meiosis occurs right after crossing over takes place?
After crossing over takes place during prophase I of meiosis, the next phase is metaphase I. During metaphase I, homologous chromosomes align at the metaphase plate, preparing for segregation. This alignment is crucial for the reduction of chromosome number and the promotion of genetic diversity in the resulting gametes.
When does crossing over occur im meiosis?
it takes place in the metaphase
Which phase of meiosis occurs right after crossing over?
Before crossing over, interphase I takes place. Crossing over occurs during prophase I. Metaphase I occurs after prophase I.
