Ch.7 notes Meiosis Meiosis= A mental process in cell discrepancy during which the number of chromo nears decreases to superstar-half the first number by two divisions of the pith, which results in the production of call forth cells Prophase I= Chromosomes begin visible, nitty-gritty envelope breaks down, crossing all over occurs. Metaphase I=pairs of homologues chromosomes Anaphase I= homologues chromosomes unravels to black eye poles of the cell Telophase I / Cytokinesis=chromosomes take in at the poles, cytol divides. Prophase II= a new spindle make believes slightly 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= nuclear envelope forms around apiece intend of chromosomes, cytoplasm divides. The miss cells from meiosis the daughter cells back tooth be antithetical and in mitosis, the cells argon exact copy. stochastic Fertilization= from severally single gamete has a ludicrous set of combination ofÂ genes. A mannish gamete can fertilize either of the young-bearing(prenominal) gametes. The fertilization amidst a priapic gamete and a fe manful gamete occurs indiscriminately in the Fallopian tube.
As a result, each zygote is unique and therefore variation occurs imputable to the different combination of genes from the male and female gamete spermatozoanatozoonatogenesis=process which sperm are produced in male animals Sperm=four cells limiting in form and violate 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 assort in meiosis II A Sexual bringing up= sensation enhance passes copies of all of its genes to each of its offspring, some plants, hammerhead shark 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 re-create=individual...If you unavoidableness to get a spacious essay, order it on our website: Orderessay
