WebbIn meiosis I, crossing over of homologous chromosomes occurs during prophase I, allowing exchange of genetic material between the two parental genomes. In metaphase I, homologous chromosomes are pulled to opposing poles of the cell and during anaphase I, the chromosomes are independently assorted.

Just one egg is produced from the four haploid cells that result from meiosis. The single egg is a very large cell, as you can see from the human egg also shown in Figure 7.5. 5.

WebbMeiosis is a form of nuclear division that results in the production of haploid cells from diploid cells. It produces gametes in plants and animals that are used in sexual reproduction. It has many similarities to mitosis however it has two divisions: meiosis I and meiosis II. Within each division there are the following stages: prophase ...

WebbMeiosis contains two separate cell divisions, meaning that one parent cell can produce four gametes (eggs in females, sperm in males). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.
