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

Benjamim XCuinmi х Х х х Xх хх о о XX O 2. A color-blind man married a normal woman. Their daughter, who was phenotypically normal, married a normal man and the couple produced three children, a normal boy, a color-blind boy, and a color-blind girl. Further examination indicates that this girl has two X chromosomes. Explain the origin of the color- blind girl.а. Indicate where independent assortment takes place. b. Label when the cell(s) are diploid or haploid. с. Indicate the number of chromosomes in each cell. d. Label Interphase, Prophase I, Metaphase I, Anaphase I, Telophase I, Meiosis I, and Meiosis II.
- Identify the stages of meiosis described by the following meiotic events/conditions/terms. Write prophase I, metaphase I, anaphase I, telophase I, prophase II, metaphase II, anaphase II, or telophase II. In case the events are found in both stages, write the stages both. 1. Formation of chiasma 2. Each chromatid is considered as full-fledged chromosome. 3. Chromosomes begin to pair off. 4. Spindle microtubules start to attach to the centromere. 5. Tetrads are aligned at the middle of the cell. 6. The sister chromatids separate. 7. Produce 2 haploid daughter cells. 8. The chromosomes line up at the middle of the cell. 9. The sister chromatids move together to the opposite poles. 10. The chromatids reach the poles. 11. The chromosomes in each daughter cell are still duplicated.12. Spindle microtubules attach in the centromere of each haploid daughter cell. 13.Explain the process of the following: a. The normal segregation of chromosomes during Meiosis 1 and Meiosis 2 in MALE. b. The abnormal segregation of chromosomes during Meiosis 1 and Meiosis 2 in FEMALE.a. If cell division during gametogenesis is non-meiotic, what is its consequence to the future generations of diploid organisms? b. How does non-disjunction in meiosis lead to numerical chromosomal aberration?
