I do GP Biology (9th year here), and I'm on the quiz "Week 13-Meiosis: The Life Cycle of S-x Cells". I got the question What happens during crossing over? The answer was "homologous chromosomes trades pieces of DNA." Hope this was the answer you're looking for!

What stage does chromatin condense to chromosomes?
During mitosis, chromosomes are in their most condensed form during metaphase
Chromosomes form during what?
Chromosomes form during Prophase of Mitosis.
What results in the exchange of alleles and produces now combinations of alleles?
Crossing over during prophase I of meiosis.
What process during meiosis leads to genetic variation?
DNA organizes into chromosomes within the nucleus
What happens to cytoplasm during interphase?
nothing happens during interphase. That is when the cell starts the process of the cell cycle and goes into prophase.
What results from the process of crossing over during prophase I?
During crossing-over, chromosomes of a homologous pair breaks and exchange genes.
How genatic material can be rearnged during meiosis?
By crossingover.
What results from the process of crossing over during prophase 1?
It results in the exchange of alleles between homologous chromosomes and produces new combination's of alleles.
During which process does crossing-over occur?
crossing over occurs in meiosis I, specifically during prophase
What process takes place during prophase?
Chromosomes are copied.
What results from the process of crossing-crossing during prophase 1?
During crossing over, the pairs of homologous chromosomes exchange pieces of their sister chromatids with one another. This process results in every sister chromatid being genetically different from one another. Eventually, meiosis II results in four non-identical haploid cells called gametes, each containing one set of chromosomes. Crossing over during prophase I greatly increases the possible genetic combinations for an offspring.
What process helps make meiotic cells genetically different and occurs during prophase but not during prophase 2?
Th process of independent orientation of chromosomes while in their tetrad forms. But, the more important process that also happens in prophase I is the process of crossing over where chromosomes, male and female, exchange regions of the chromosomes, one with the other.
What stage does chromatin condense to chromosomes?
During mitosis, chromosomes are in their most condensed form during metaphase
Genetic recombination is due to what event that occurs during prophase?
There are five substages to prophase I. Genetic exchange happens during the fourth stage, Diplonema. This process is also called crossing over.
This is the process in which two chromosomes exchange DNA during prophase of meiosis?
This process is called crossing over .
Chromosomes form during what?
Chromosomes form during Prophase of Mitosis.
During which phase does the chromatin condense into chromosomes?
The chromosomes coil up and condense during prophase
