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:
Question

Transcribed Image Text:In the diagram below, white represents maternal information and black represents paternal information. This stage is:
- Mitosis
- Meiosis 1
- Meiosis 2
### Diagram Explanation:
The diagram displays a genetic representation of chromosomes during a cellular division process. Each chromosome is divided into sections representing genetic information from both maternal (white) and paternal (black) origins. The chromosomes are labeled with letters: A, C, and D, with different combinations indicating distributed genetic information.
In this specific diagram:
- Two pairs of chromosomes (each appears as two sister chromatids joined at the centromere) are shown.
- Each pair has one chromatid from the maternal side and one from the paternal side, demonstrating the crossing over of genetic material.
- The arrangement of chromosomes indicates one of the stages in cell division, particularly related to the meiotic process.

Transcribed Image Text:**Title:** Analysis of Chromosomal Stage in Cell Division
**Description:**
In the diagram below, white represents maternal information and black represents paternal information. The stage depicted in the diagram involves a pairing and alignment of homologous chromosomes, each labeled with different gene loci:
- Chromosome 1:
- Left: Black (paternal) with gene label "A"
- Right: White (maternal) with gene label "A"
- Chromosome 2:
- Left: White (maternal) with gene label "C"
- Right: Black (paternal) with gene label "C"
- Chromosome 3:
- Left: Black (paternal) with gene label "D"
- Right: White (maternal) with gene label "d"
This diagram represents a stage where homologous chromosomes are aligned in a manner characteristic in the process of crossing over during meiosis. The white and black colors indicate the different parental origins of chromosomal segments.
**Question:** This stage is most representative of which cell division process?
- Mitosis
- Meiosis 1
- Meiosis 2
The correct answer is **Meiosis 1**, specifically at the stage where homologous chromosomes pair up and exchange genetic material, preparing for the first meiotic division.
