By crossingover.
During mitosis, chromosomes are in their most condensed form during metaphase
During crossing-over, chromosomes of a homologous pair breaks and exchange genes.
The chromosomes coil up and condense during prophase
The pairing up of maternal and paternal chromosomes during meiosis happens in the prophase I stage. This pairing is called synapsis and results in the formation of a structure called a tetrad.
Crossing over occurs during Prophase I of meiosis.
Crossing over during prophase I of meiosis.
No, crossing over occurs during prophase 1 of meiosis, not prophase 2.
It results in the exchange of alleles between homologous chromosomes and produces new combination's of alleles.
prophase I
The chromosomes in a cell's nucleus are only visible during the part of the cell cycle known as prophase. Prophase is the stage of mitosis in which chromatin condensation occurs.
