meiosis- making gametes 1. shockting 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 degage (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 spear carrier chromo. Prophase I- failly chromo. Pairs with its corresponding homologous chromo. To form a tetrad Metaphase I- spindle 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 deuce haploid (N) daughter cells, severally with half the consequence of chromo. As the first Metaphase II- chromo. Line up in a similar way to the metaphas e stage of mitosis. Anaphase II- sister chromoatids separate and regard 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 oft 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 but the same in genetic makeup as the original parent cell, with the same dna. Whereas, in meiosis, the cells are not the same, hence the purpo se of meiosis, to make new cells. The whole ! canonical precept 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 orbit of heredity(how traits are passed) Trait-characteristics...If you want to get a full essay, assign it on our website: OrderEssay.net
