Oogenesis chromosomes
Web20 de abr. de 2024 · An oocyte is an immature egg (an immature ovum). Oocytes develop to maturity from within a follicle. These follicles are found in the outside layer of the ovaries. During each reproductive cycle, several follicles begin to develop. Typically, only one oocyte each cycle will become a mature egg and be ovulated from its follicle. WebOogenesis. The process of producing eggs in the ovary is called oogenesis. Eggs, like sperm, are haploid cells, and their production occurs in several steps that involve different types of cells, as shown in Figure below. You can follow the process of oogenesis in the figure as you read about it below. Oogenesis.
