The G1, S and G2 phases together are called interphase. The M phase completes the cell cycle. ’M’ could be mitosis or meiosis depending on the type of cell. For the zygote, the goal is to make more somatic cells. Therefore, it goes through mitosis and gives rise to two daughter cells.

12 wrz 2023 · Both mitosis and meiosis start out with DNA replication, but with different ultimate goals. Mitosis : DNA replication produces identical sister chromatids. Meiosis : DNA replication also occurs, but crossing-over in Prophase I will create genetic diversity.
M phase involves two distinct division-related processes: mitosis and cytokinesis. In mitosis , the nuclear DNA of the cell condenses into visible chromosomes and is pulled apart by the mitotic spindle, a specialized structure made out of microtubules.
31 lip 2022 · Learning Objectives. By the end of this section, you will be able to: Describe the behavior of chromosomes during meiosis. Describe cellular events during meiosis. Explain the differences between meiosis and mitosis. Explain the mechanisms within meiosis that generate genetic variation among the products of meiosis.
The fate of germ cells is dictated by the somatic environment. In both the developing ovary and the testis, germ cells undergo mitotic proliferation prenatally, but the time of entry into...
Learning Objectives. You will be able to describe mitosis and meiosis as the process to make cells : How mitosis transfers genetic material to offspring. Recognize the steps in mitosis. Understand the cell cycle. Cell differentiation creates tissues. Unregulated cell division can lead to cancer.
The meiosis cell cycle has two main stages of division -- Meiosis I and Meiosis II. The end result of meiosis is four haploid daughter cells that each contain different genetic information from each other and the parent cell.
