Q. Indicating the name and respective ploidy of each involved cell how can the formation of egg cells from germ cells be described?

The formation of egg cells begins with a germ cell called as oogonium (2n) that undergoes mitosis and gives birth to the oocyte I (2n). The oocyte I undergoes meiosis I that although is interrupted at prophase and after puberty during each menstrual cycle an oocyte I finishes the meiosis I and generate one oocyte II (n) and the first polar body (n) with fecundation the oocyte II then undergoes meiosis II and produces the mature egg cell (n) and the second polar body (n).
