During meiosis, when crossing-over occurs between two homologous chromosomes, it does not happen at a single point, but rather two points with a stretch of DNA in between. What are the two junction points called? What is the region between the two points called and what is different about this region compared to how double-stranded DNA usually is? If the region described in b.) is located within a gene and the two homologues have different alleles of this gene, what might happen that is a direct violation of Mendel’s first law? (Describe the process with 2-3 sentences of detail.)

in metaphase 1 of meiosis, the homologous chromosomes line up side by side along the equator so that crossing over can occur between the homologous pairs and the homologous chromosomes can be pulled to opposite poles during anaphase 1. in mitosis, by contrast, homologous chromosomes line up single file along the equator. what benefits are derived from these two different ways that homologous chromosomes are positioned at metaphase in meiosis and mitosis?
