By crossingover.
During crossing-over, chromosomes of a homologous pair breaks and exchange genes.
During mitosis, chromosomes are in their most condensed form during metaphase
Chromosomes form during Prophase of Mitosis.
The chromosomes coil up and condense during prophase
Crossing over during prophase I of meiosis.
Crossing over occurs during Prophase I of meiosis.
yes, during prophase
Tetrads line up in the middle of the cell during metaphase I.
It results in the exchange of alleles between homologous chromosomes and produces new combination's of alleles.
There is still only 1 cell during prophase.
