Ch.7 notes Meiosis Meiosis= A summons in kiosk disagreement during which the number of chromosomes decreases to one- fractional the original number by both divisions of the pith, which results in the production of sex cells Prophase I= Chromosomes pay back visible, nucleus envelope breaks down, crossing over occurs. Metaphase I=pairs of homologues chromosomes Anaphase I= homologues chromosomes moves to setback poles of the cell Telophase I / Cytokinesis=chromosomes gather at the poles, cytol divides. Prophase II= a new spindle forms around the chromosome Metaphase II= Chromosomes argument up at the equator Anaphase II= Centromeres divide, chromatids move to opposite poles of the cell. Telephase II / Cytokinesis= nuclear envelope forms around from each one set of chromosomes, cytoplasm divides. The daughter cells from miosis the daughter cells can be antithetic and in mitosis, the cells are exact copy. Random Fertilization= from each one gamete has a uniq ue set of combination of genes. A masculine gamete can fertilize any of the young-bearing(prenominal) gametes. The fertilization amidst a male gamete and a feminine gamete occurs randomly in the Fallopian tube.
As a result, each zygote is unique and therefore mutation occurs due to the different combination of genes from the male and female gamete spermatozoonatogenesis=process which sperm are produced in male animals Sperm= 4 cells change in form and develop a can buoy to becom e male gametes called sperm. Oogenesis= pr! ocess which gametes are produced in female animals Ovum=egg, which comes from the uneven cell split in meiosis II A Sexual Reproduction= single provoke passes copies of all of its genes to each of its offspring, some plants, hammerhead shark and the dim tip shark are examples Sexual Reproduction= carmine parents each form reproductive cells that have one half the number of chromosomes. Humans, some plants and mostly everything else are examples Clone=individual...If you unavoidableness to expire a full essay, order it on our website: BestEssayCheap.com
