During the process of gametogenesis many structures are formed which are listed below. Select the cells which are diploid.
Gametogenesis is a process of forming mature haploid gametes formed from precursor cells (germ cells).
Oogonia are a diploid structure which upon maturation form primordial cells present in ovaries.
Primary, secondary polar bodies and spermatids are formed only after going through meiosis division (reductional division), thus they all are haploid in nature.
