Mitosis And Meiosis Diagram Phases. Meiosis consists of two divisions both of which follow the same stages as mitosis prophase metaphase anaphase telophase p i. Labeled diagram mitosis is a process of cell division which results in the production of two daughter cells from a single parent cell.
Diagram and describe the key events that occur during the phases of meiosis 3. Excellent animations showing the stages of mitosis meiosis and many more key biological processes. Meiosis ii divides each chromosome into two copies much like mitosis.
From a preceding mitotic division the oogonium spermatogonium enters meiosis with diploid 2n chromosomes but tetraploid 4n dna chromosomes then duplicate to produce sister chromatids or homologous dyads.
In addition the chromosomes in each matching pair swap some genetic material before they are parted in a process called crossing over. From a preceding mitotic division the oogonium spermatogonium enters meiosis with diploid 2n chromosomes but tetraploid 4n dna chromosomes then duplicate to produce sister chromatids or homologous dyads. Dyad pairs align to create tetrads non sister chromatids connect and trade sections at a chiasma a process called crossing over. See our detailed explanation below.
