Crossing over is a process that happens between homologous chromosomes in order to increase genetic diversity. During crossing over, part of one chromosome is exchanged with another.
Crossing over produces genetic variations in daughter cells, consequently leading to genetically dissimilar offspring.
Explanation:
Crossing Over:
A process that occurs during the Prophase 1 of meiosis 1, a type of cell division that takes place in germ cells (reproductive cells) to produce gametes for reproduction.
Crossing over, by definition, is the exchange of chromosomal segments between non-sister chromatids of chromosomes.This occurs through a process called homologous recombination.
<u>Crossing over produces a variety of gametes with characteristics different from the parents.</u>
In terms of evolution, this process introduces genetic variations that can help the organism better adapt to its environment.
