Oocytes are the oocytes that carry out meiosis during ovulation. They are divided into primary oocytes, secondary oocytes and mature oocytes, which are the products of the first and second meiosis after the division of oocyte differentiation and DNA replication, respectively.
The male germ cell and female germ cell combine to form a zygote. A zygote that undergoes multiple cell divisions and differentiation to form a embryo with the ability to develop into a biological adult is called an embryo.
