WebOct 8, 2024 · Interphase. Meiosis is preceded by an interphase consisting of the G 1, S, and G 2 phases, which are nearly identical to the phases preceding mitosis. The G 1 phase is the first phase of interphase and is focused on cell growth. In the S phase, the DNA of the chromosomes is replicated. Finally, in the G 2 phase, the cell undergoes the final … WebMitochondria and chloroplasts (and the genes they carry) are randomly distributed to daughter cells during mitosis and meiosis. When the cell divides, the organelles that happen to be on opposite sides of the cleavage furrow or cell plate will end up in different daughter cells ^3 3 . Single-parent inheritance.

Each daughter cell gets one centrosome from the parent cell during cell division. The centrosome is then copied during the cell cycle, so that the cell can give one to each daughter cell when it divides. WebJun 8, 2024 · Meiosis begins with a cell called a primary spermatocyte.
