Understanding:
• Crossing over is the exchange of DNA material between non-sister homologous chromatids
• Crossing over produces new combinations of alleles on the chromosomes of the haploid cells
When chiasmata form between bivalents in prophase I, DNA can be exchanged between non-sister homologous chromatids
This exchange of genetic material is called crossing over and produces new allele combinations on the chromosomes
These chromosomes that consist of genetic material from both homologues are called recombinant chromosomes
Crossing over results in new combinations of alleles in haploid cells and thus increases the genetic diversity of potential offspring
