In contrast, meiosis is considered a “reductional” form of cell division that occurs in diploid germ cells. During meiosis, a diploid germ cell undergoes two cell divisions to produce four haploid gamete cells (e.g., egg or sperm cells), which are genetically distinct from the original ...
ZP3 starts to express in the oocytes of primary follicles whose formation occurs after birth, however, in our previous study Oog1 expression starts in oocytes at E15.5. The gap of the expression between ZP3 and Oog1 would prevent the functional analysis of Oog1 during oogenesis and ...
