compare the homologous has chromosomes to the chromatids they become at the end of mitosis due to crossing over.Explain the importance of crossing over.
I have some things that may help, but i don't know for sure. "Each chromosome still has two sister chromatids, but the chromatids of each chromosome are no longer identical to each other" (https://www.khanacademy.org/science/biology/cellular-molecular-biology/meiosis/a/phases-of-meiosis?modal=1) "Crossing over is essential for the normal segregation of chromosomes during meiosis. Crossing over also accounts for genetic variation, because due to the swapping of genetic material during crossing over, the chromatids held together by the centromere are no longer identical." that's basically what the crossing over is ig and why it may be important. This is not my strong subject but i hope this helps
thanks for the help
anytime ^^
