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.
Crossing over occurs during fertilization. This is the mixing of alleles from each of the parents in order to make the offspring.
The result of crossing over is genetic diversity. More specifically, it is a hybrid chromosome with a unique pattern of genetic material. Does this answer help?
During crossing-over, the genetic material from homologous chromosomes is swapped. This leads to a recombination of the genes. Simple example: Originally - ABCD alleles on one and abcd on the other. After crossing over - ABCd and abcD This creates offspring with non-parental phenotypes (traits), which are known as recombinants.
COV crossing over value
crossing over or swaping genetic material
it takes place in the metaphase
Crossing-over takes place between homologous chromosomes during meiosis.
Before crossing over, interphase I takes place. Crossing over occurs during prophase I. Metaphase I occurs after prophase I.
Metaphase 1
Crossing over occurs during fertilization. This is the mixing of alleles from each of the parents in order to make the offspring.
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.

it takes place between homologous chromosomes and results in new gene combinations
It would appear you are speaking of crossing over which takes place in 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.
Freedom of genetic characters to move independently from parents to the gametes by the process of crossing over which takes place during meiosis.
