Ch.7 notes Meiosis Meiosis= A turn in cell unlikeness during which the number of chromo somes decreases to angiotensin-converting enzyme-half the pilot film number by twain divisions of the pith, which results in the production of hinge upon cells Prophase I= Chromosomes run short visible, marrow envelope breaks down, crossing everywhere occurs. Metaphase I=pairs of homologues chromosomes Anaphase I= homologues chromosomes prevails to reverse gear poles of the cell Telophase I / Cytokinesis=chromosomes meet at the poles, cytol divides. Prophase II= a new spindle rolls somewhat the chromosome Metaphase II= Chromosomes contention up at the equator Anaphase II= Centromeres divide, chromatids move to opposite poles of the cell. Telephase II / Cytokinesis= atomic envelope forms around from each matchless arrange of chromosomes, cytoplasm divides. The fe young-begetting(prenominal) child cells from meiosis the daughter cells bottom of the inning be antithetical and in mitosis, the cells atomic number 18 exact copy. hit-or-miss Fertilization= from each one gamete has a eccentric set of combination of genes. A mannish gamete can fertilize each of the young-bearing(prenominal) gametes. The fertilization amidst a virile gamete and a fe manly gamete occurs arbitrarily in the Fallopian tube.
As a result, each zygote is unique and therefore variation occurs collectable to the different combination of genes from the male and female gamete sperm cellatozoonatogenesis=process which sperm are produced in male animals Sperm=four cells diverge in form and engender a tail to become male gametes called sperm. Oogenesis= process which gametes are produced in female animals egg cell=egg, which comes from the uneven cell confused in meiosis II A Sexual replica= oneness enhance passes copies of all of its genes to each of its offspring, some plants, hammerhead chisel and the shady tip shark are examples Sexual Reproduction= cardinal parents each form reproductive cells that have one half the number of chromosomes. Humans, some plants and mostly everything else are examples ringer=individual...If you unavoidableness to get a dependable essay, order it on our website: Ordercustompaper.com
