Question

What happens during prophase 1 and metaphase 1 and how do these phases play an important role in the genetic diversity of the daughter cells produced?

Answer 1

During prophase 1, Chromosomes become visible and crossing-over start occurring. Another thing that happens is the disappearance of the nucleolus and the disappearance of the nuclear envelope. The meiotic spindle then forms.

“During metaphase 1, the pairs of chromosomes (bivalents) become arranged on the metaphase plate and are attached to the now fully formed meiotic spindle. The centrioles are at opposite poles of the cell.”
