Study Notes
- A quick review of mitosis, its function, what logically has to happen, and the steps (PMAT) is important when studying meiosis.
Stages of Mitosis
- Mitosis includes interphase, early prophase, later prophase, metaphase, anaphase, telophase, interphase, and cytokinesis
- Interphase cells carry out normal activities, and chromosomes duplicate.
- Early prophase cells see the nuclear envelope and nucleolus disappear, chromatin becomes visible.
- Late prophase chromosomes shorten and thicken; the spindle forms, centrioles move to opposite poles, kinetochores attach to microtubules.
- Metaphase sees spindle fibers attach to the kinetochores of chromosomes, lining them up on the cell's midplane.
- During anaphase, chromatids separate at centromeres, and a group of chromosomes moves toward each opposite pole.
- Telophase sees chromosomes arrive at the poles, nuclear envelopes form, producing two daughter cells after cytokinesis.
- Daughter cells formed are genetically identical to the parent cell.
- Cytokinesis involves a cleavage furrow in animal cells and the formation of a cell plate in plant cells.
Asexual Reproduction
- Offspring from asexual reproduction have hereditary traits identical to a single parent.
- Mitosis is the basis of asexual reproduction.
Sexual Reproduction
- Sexual reproduction leads to the creation of a fertilized egg or zygote when the gametes join.
- Meiosis serves as the foundation for this process.
Functions of Meiosis
- The function of meiosis is to make haploid gametes, such as eggs and sperm.
- Meiosis is the reason for individual variability.
- Gametes from different parents can eventually join to produce a fertilized egg, also known as a zygote.
Karyotype
- A karyotype is a picture of the overall structure and size of the chromosomes in a genome.
- A karyotype includes homologous chromosomes, centromeres and sister chromatids.
