WebWhat is Oogenesis? The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase. Gametogenesis WebAn example is the amphibian Xenopus laevis. In somatic cells, the ratio of nuclear DNA:mitochondrial DNA is 100:1. In the fully-grown oocyte, that ratio has reversed to a range from 1:1 to 1:100. During mitochondrial replication in early oogenesis, mitochondria cluster around the nucleus to form a structure called the mitochondrial cloud.
