Learning about the crossing over of DNA in Prophase 1 of Meiosis was hard. Thining back on it, I wish I learned earlier that the crossing over happens between haploid pairs. Haploid pairs are the pairs of chromosomes, one form your father and one from your mother. There are 23 haploid pairs in a human body. The haploid pairs form what is known as a tetrad. I had believed that crossing over could happen between any two chromosomes. This would not work because then some people would be missing important genetic info like how to make protiens. The discussion about Sandra, Mike, and Chris Serbert helped me learn the idea. It showed how no matter what, every sperm, egg, or pollen cell made in Meosis is different.
