Consult Figure 4, which shows the distribution of chromosome segregation for a cell with genotype M/m; B/b. For each panel, state whether the illustration is possible for mitosis, meiosis I, meiosis II, or not possible for the genotype. Assume no crossing over. Panel A: Possible during mitosis Possible during meiosis I Possible during meiosis II Not possible for the stated genotype Panel B: Possible during mitosis Possible during meiosis I Possible during meiosis II Not possible for the stated genotype
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:
Consult Figure 4, which shows the distribution of chromosome segregation for a cell with genotype M/m; B/b. For each panel, state whether the illustration is possible for mitosis, meiosis I, meiosis II, or not possible for the genotype. Assume no crossing over.
Panel A:
- Possible during mitosis
- Possible during meiosis I
- Possible during meiosis II
- Not possible for the stated genotype
Panel B:
- Possible during mitosis
- Possible during meiosis I
- Possible during meiosis II
- Not possible for the stated genotype
