light reflex- making gametes 1. shortenedting chromosomes by ½ 2.genetic diversity MI- everything happens in PAIRS PI- pairs amount unneurotic (tetrad) -crossing over can happen MI- pairs in middle (genetic diversity) AI- pairs detached (independent assort. (Genetic assort) Mitosis-2 diploid identical girl cells Meiosis- haploid different daughter cells PHASES OF litotes I Interphase I- cells undergo round of DNA replication, forming double chromo. Prophase I- failly chromo. Pairs with its corresponding homologous chromo. To form a tetrad Metaphase I- pergola 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 two haploid (N) daughter cells, severally with half the keep down of chromo. As the accepted Metaphase II- chromo. Line up in a similar way to the met aphase stage of mitosis. Anaphase II- sister chromoatids separate and go forward 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 some(prenominal) 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 exactly the same in genetic makeup as the origi nal parent cell, with the same dna. Whereas,! in meiosis, the cells are not the same, thusly the purpose of meiosis, to make new cells. The whole canonical dominion 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 pick up of heredity(how traits are passed) Trait-characteristics...If you want to get a full essay, shape it on our website: OrderCustomPaper.com
