Week 1 Reflection

For the week of 1/7 - 1/10, I learned about Meiosis and Sexual Reproduction. I learned that Meiosis is eight steps. The eight steps of Meiosis are Prophase 1, Metaphase 1, Anaphase 1, Telophase 1 & Cytokinesis, Prophase 2, Metaphase 2, Anaphase 2, Telophase 2 & Cytokinesis (in order). Meiosis starts with one diploid cell and ends with four different haploid cells. I learned that humans have a full set of chromosomes at the number 46. 46 is diploid, so the haploid number is 23 chromosomes. I learned that 23 chromosomes are from the egg,(the mom) and 23 chromosomes are from the sperm(the dad), for a total of 46. The joining of sperm and egg is called fertilization. I also learned about the differences between Meiosis and Mitosis.
