Guida verificata passo dopo passo1
Understand that meiosis is a special type of cell division that reduces the chromosome number by half to produce gametes (sperm or egg cells).
Recall that meiosis consists of two sequential rounds of cell division: meiosis I and meiosis II.
In meiosis I, homologous chromosomes are separated into two daughter cells, reducing the chromosome number from diploid to haploid.
In meiosis II, the sister chromatids of each chromosome are separated, similar to mitosis, resulting in four haploid cells.
Therefore, a germ cell must undergo two rounds of cell division during meiosis to produce four gametes.
