Question
What happens during crossing over? Select 2
chiasma formation between of non-sister chromatids of homologous and exchange of the genetic material.
results in recombinant chromosomes that lead to increased variation
polyploidy of chromosome sets occurs during Metaphase I
results in diploid cells being made that decrease the variation in offspring

The correct selections regarding what happens during crossing over are:
1. **Chiasma formation between non-sister chromatids of homologous and exchange of the genetic material.**
2. **Results in recombinant chromosomes that lead to increased variation.**
Crossing over occurs during prophase I of meiosis, where homologous chromosomes exchange segments of DNA, resulting in new combinations of genes and increased genetic diversity in the resulting gametes.
