Meiosis Terms Anaphase 1 - The fourth stage of the first meiotic division (meiosis I), during which maternal and paternal homologous pairs are separated on microtubules. Anaphase 2 - The fourth stage of the second meiotic division (meiosis II), during which either maternal or paternal sister chromatids are separated on microtubules. Chiasma - The region of physical linkage between maternal and paternal homologous pairs during genetic reassortment. Marks the location of crossover between two nonsister chromatids. Diploid number - The total number of chromosomes present in a cell. Gametes - Cells with the haploid number of chromosomes. Gametes are created out of germ cells. The sperm and eggs involved in sexual reproduction are gametes. Genetic Reassortment - A process in which DNA packaged as a chromosome is broken and fragments are exchanged with another independent chromosome. Occurs during prophase 1 of

Unformatted text preview: meiosis. Germ cell - Cells that lead to the production of gametes. Produced by meiosis. Haploid number - The number of unique chromosomes or homologous pairs in a cell. Half the diploid number. Homologous pair - Refers to two similar chromosomes in a diploid cell. One chromosome is derived from the father gamete cell and the other from the mother gamete. Meiosis - A type of cellular reproduction that results in the formation of four haploid cells from one diploid cell. Contains two cellular divisions that follow only one round of DNA replication. The type of reproduction that produces germ cells. Metaphase 1 - The third stage of the first meiotic division (meiosis I), during which chromosomes align at the center of the cell by way of microtubule force. Metaphase 2 - The third stage of the second meiotic division (meiosis II), during which chromosomes align at the center of the cell by way of microtubule force....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
