pupillary reflex- making gametes 1. lowerting chromosomes by ½ 2.genetic diversity MI- everything happens in PAIRS PI- pairs amount together (tetrad) -crossing over can happen MI- pairs in middle (genetic diversity) AI- pairs isolate (independent assort. (Genetic assort) Mitosis-2 diploid identical miss cells Meiosis- haploid different daughter cells PHASES OF litotes I Interphase I- cells undergo round of DNA replication, forming parallel chromo. Prophase I- failly chromo. Pairs with its corresponding homologous chromo. To form a tetrad Metaphase I- arbor fibers isolate to the chromo. Anaphase I- fibers pull the homologous chromo. Towards opposite ends of the cell Telophase I & Cytokinesis-nuclear membranes form. Cell separates into 2 PHASES OF meiOSIS II Prophase II-meiosis I results in both haploid (N) daughter cells, severally with half the enactment of chromo. As the sure Metaphase II- chromo. Line up in a similar way to the metaphas e stage of mitosis. Anaphase II- sister chromoatids separate and preempt toward opposite ends of the cell Telophase II & Cytokinesis- meiosis II results in four haploid (N) daughter cells DIFF.

surrounded by M1 & M2 Meiosis I and meiosis II be very ofttimes as well except that mII produces four haploid cells from the two haploid cells that were produced in mI PURPOSE OF MEIOSIS To cut the chromosomes in half GOALS OF MEIOSIS To form gametes DIFFERENCES BETWEEN MEI/MITOSIS The two cells that come out of the division of mitosis be hardly the same in genetic makeup as the original parent cell, with the same dna. Whereas, in meiosis, the ! cells are not the same, and then the purpose of meiosis, to make new cells. The whole canonical article of faith of this is that normal cells undergo mitosis, while only conjure up cells undergo meiosis CHROMOSONAL DISORDERS Super female-XXX Turner female-XO Kleinfelters male-XXY Super male- XYY VOCAB Genetics-scientific champaign of heredity(how traits are passed) Trait-characteristics...If you want to get a full essay, devote it on our website: OrderCustomPaper.com
