1. Alisha Walls created a children’s book that simplifies the process of Meiosis for better understanding. The book answers important questions such as why we don’t look like our siblings despite our parents being the same and the definition of Meiosis. The project takes the reader step by step with characters that appear to be minions making it an interesting and fun activity for visual learners. Meiosis I precedes with Interphase wherein the DNA in the cell is duplicated resulting in two identical sets of chromosomes. The next step is Prophase where chromosomes condense, the nuclear membrane dissolves, homologous chromosomes form sister chromatids, and crossing -over begins. Metaphase follows where spindle fibers from opposing centrosomes attach to the sister chromatids (at centromeres) and align along the middle of the cell. The next step is Anaphase where spindle fibers contract and split the sister chromatids and homologous chromosomes move to opposite sides of the cell. Lastly, Telophase is where chromosomes decondense, the nuclear membrane reappears, the cell divides (cytokinesis) to create two haploid daughter cells. Meiosis II is the second division that goes through the four steps again ultimately producing four haploid daughter cells.
    Alisha Walls also includes a mnemonic for some of the steps. For example, (Pro)phase – before, and (M)etaphase – middle, (A)naphase – away or chromosomes are pulled away. Alisha Walls made sure to distinguish the difference between Meiosis I and Meiosis II with the latter having less crossing-over and a different outcome. Additionally, she included that genetic variety is a product of crossing over and independent assortment.
