Question

meiosis label these cell structures present during prophase i...

Explanation:

During Prophase I of meiosis, centrioles move to opposite poles and organize the spindle fibers. Homologous chromosomes pair up and crossing - over of chromatids occurs. The spindle apparatus forms to help with chromosome movement.

• The structure at the pole from which spindle fibers radiate is the centriole.
• The exchange of genetic material between non - sister chromatids of homologous chromosomes is crossing over of chromatids.
• The structure made of microtubules that helps move chromosomes is the spindle.
• The pairs of chromosomes with the same genes in the same order are homologous chromosomes.
