The daughter cells will have paternal or maternal chromosomes.
It is a major step in meiotic cell division during which non-sister chromatids exchange chromosomal segments, and as such, the genetic materials in the segments.
The process of crossing over happens at prophase I of meiosis I with the result being daughter cells whose chromosomes have been recombined as well as reconstructed.
Without crossing over, meiosis will end up producing daughter cells with either maternal or paternal chromosomes. The effect is that the number of genetic recombination in the daughter cells has been significantly reduced.
