AP Biology Meiosis Essay

light reflex is the operation in sexually reproducing organisms where stalls divide. The carrels produced during miosis have i-half the chromosome number as the original cell. There be cardinal cell divisions in light reflex, meiosis l and meiosis ll. These cell divisions produce 4 hapolid daughter cells. Haploid cells ingest only iodin set of chromosomes, which is written as n. Meiosis consists of nine phases. In meiosis the interphase l the chromosomes replicate and the centrosome duplicates in one diploid cell. Diploid cells have two sets of chromosomes, they received one from from each one parent. During prophase l the atomic envelope fragments and spindle microtubules form betwixt the centrosomes. Homologous chromosomes duo to make two baby chromatids. This is called synapsis. Chromatids of homologous pairs exchange segments when they buzzer ringer over. At metaphase l, the pairs line up on the metaphase graduated table. Microtubules from one perch attach to the kinetochore of one homologous chromosome, plot microtubules from the other pole attach to the kinetochore of the other pair. During anaphase l the microtubules bum shorter pulling the homologous pairs towards opposite poles. At telophase l two monoploid cells form exactly the chromosomes are calm double. Meiosis ll separates the sister chromatids. During prophase ll the sister chromatids in each cell begin moving towards the equator. At metaphase ll the chromosomes align on the metaphase plate in each cell. The process of anaphase ll pulls the sister chromosomes to opposite poles in each cell.

During telophase ll each cell forms a nuclei and cytokinesis splits the cells apart. F our genetically different haploid cells are ! produced. Independent assortment is differences amidst the genes. conversion can occur in meiosis when the chromosomes cross over and during stochastic fertilization. Random fertilization is when a gamete from the mother unites with the haploid from the father to produce... It was quite informative, but you should fix the layout of your text because it is devil to read it when the distances between the sentences is big.
