Are oogonia haploid or diploid?

Haploid cells:

1. Haploid cells have one single set of chromosomes.
2. Sex cells or gametes are haploid cells.
3. These cells are produced through meiosis.
4. When both males and females fuse together while fertilization, they form diploid cells.

Diploid cells:

1. Diploid cells are two sets of chromosomes.
2. They are formed due to the fusion of haploid cells.
3. Most mammals are diploid.
4. Mammals have two homologous copies of each chromosome.

Oogonia:

1. Oogonia are diploid cells and they are equal to spermatogonia in males.
2. Oogenesis begins when oogonium (diploid number) undergoes mitosis to form primary oocytes (diploid number).
3. Oocytes proceed to primary oocytes then secondary oocytes.
