Diagram showing the reduction in number of the chromosomes in the process of maturation of the ovum; the process is known as meiosis Main article: Oogenesis The formation of an oocyte is called oocytogenesis, which is a part of oogenesis. [ 1 ]
Oogenesis starts with the process of developing primary oocytes, which occurs via the transformation of oogonia into primary [oocyte]s, a process called oocytogenesis. [11] From one single oogonium, only one mature oocyte will rise, with 3 other cells called polar bodies. Oocytogenesis is complete either before or shortly after birth.

On this list, lectotypes are given their own entries. Paralectotype(s): When a lectotype is designated from a series of syntypes, the remaining syntypes become paralectotypes as part of a reorganized type series. On this list, paralectotypes are noted alongside the list entry for the lectotype of their respective series.
This article contains a list of organs in the human body. It is widely believed that there are 79 organs (this number goes up if you count each bone and muscle as an organ on their own, which is becoming a more common practice [1] [2]); however, there is no universal standard definition of what constitutes an organ, and some tissue groups' status as one is debated.

During follicular development, primordial follicles undergo a series of critical changes in character, both histologically and hormonally. First they change into primary follicles and later into secondary follicles. The follicles then transition to tertiary, or antral, follicles. At this stage in development, they become dependent on hormones ...
Example of a pedigree chart using Ahnentafel numbering. A pedigree chart is a diagram that shows the occurrence and appearance of phenotypes [jargon] of a particular gene or organism and its ancestors from one generation to the next, [1] [2] [3] [unreliable source?] most commonly humans, show dogs, and race horses.
