Genetics
Test 3
| Question | Answer |
|---|---|
| Bivalent | pair of replicated homologous chromosomes in phrophase I undergoing synapsis |
| Synaptonemal complex | complex of proteins that assemble between nonsister chromatids that allows crossing over to occur |
| Crossing over | exchange of genetic info btw nonsister chromatids; has potential to create new combinations of alleles that were not present in parent DNA |
| Chiasmata | physical connection btw nonsister chromatids that are the result of crossing over, important for proper chromosome segregation in meiosis |
