WebJun 17, 2016 · Jun 17, 2016 Meiosis is the type of cell division that produces gametes. Explanation: It involves two phases of cell division to produce four haploid cells. Meiosis 1 consists of Prophase 1 - Homologous chromosomes pair up and crossing over occurs which is vital for genetic variation. WebUpon the completion of telophase 1, the cells enter interphase, the period of time in-between the two cycles of division where the cell readies itself to be divided a second time.It’s important to note that the DNA of the cell …

WebMeiosis I, the first meiotic division, begins with prophase I. During prophase I, the complex of DNA and protein known as chromatin condenses to form chromosomes. The pairs of … WebMeiosis is the mechanism used to reduce diploid cells to haploid gametes while introducing genetic diversity. Prior to meiosis, chromosomes are replicated in S-phase to ensure proper number of chromosomes in the resulting gametes. WebThe key difference between metaphase 1 and 2 is that in metaphase 1, homologous chromosomes pair up at the metaphase plate while in metaphase 2, single chromosomes line up at the metaphase plate. Meiosis is the process that converts a diploid cell into four haploid cells during the gamete formation. how is heat energy measured
