Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:
Step by step
Solved in 2 steps
- Construct a table similar to that in Figure 2.12 for the different stages of meiosis, giving the number of chromosomes per cell and the number of DNA molecules per cell for a cell that begins with 4 chromosomes (two homologous pairs) in G1. Include the following stages in your table: G1, S, G2, prophase I, metaphase I, anaphase I, telophase I (after cytokinesis), prophase II, metaphase II, anaphase II, and telophase II (after cytokinesis).List 2 events that happen in meiosis that do not happen in mitosis and explain what happens during these events.Construct a table for the different stages of meiosis, giving the number of chromosomes per cell and the number of DNA molecules per cell for a cell that begins with 4 chromosomes (two homologous pairs) in G1.

- 1)Discusses why Meiosis I is referred to as reduction division and why Meiosis II is essentially like Mitosis. 2)Discusses where problems are likely to occur in Meiosis and what these problems could lead to.Examine the diagram below and answer the following questions. a) What specific stage of meiosis is this cell in? b) Exactly how many chromosomes will be in each of the 4 resulting gametes?Consider a diploid cell that has 2 n = 4 chromosomes: one pair of metacentric chromosomes and one pair of acrocentric chromosomes. Suppose that this cell undergoes nondisjunction, giving rise to an autotriploid cell (3 n). The triploid cell then undergoes meiosis. Draw the different types of gametes that could result from meiosis in the triploid cell, showing the chromosomes present in each type. To distinguish between the different metacentric and acrocentricchromosomes, use a different color to draw each metacentric chromosome; similarly, use a different color to draw each acrocentric chromosome.

- A simple diagram indicating the alterations in genetic content throughout mitosis is shown in the attached picture. Please prepare a similar diagram for meiosis, starting with a diploid cell in G1 (like the picture). Include all of the cells generated at each stage.Which statement is true of meiosis? 1)two identical cells in both divisions 2)the first division produces haploid cells and the second produces diploid cells 3)the first division produces diploid cells and the second produces haploid cells 4) the products of both meiotic divisions are haploidBriefly explain why there is no interphase in between Meiosis I and Meiosis II.
