Summary edit
| Description | Figure 1. Cartoon representation of gonadogenesis. (A) Cartoon representation of fertilization and the embryonic germ line. Oocyte and sperm meet and fertilization initiates embryonic development. Germline lineages are depicted in yellow. (B) Cartoon representation of post-embryonic hermaphrodite gonad development. Comparative size of gonads at different stages is not to scale. Germline color scheme: yellow mitotic region, light green transition (early prophase of meiosis I), dark green pachytene, dark blue spermatogenesis, and pink oogenesis. The mitosis/meiosis border is indicated in the late-L3 and late-L4 by light green arrows. In the adult, the mitosis/meiosis border is not sharp (mitotic and meiotic nuclei are interspersed at the border) as indicated here by a yellow/green color gradient. Somatic gonad color scheme: red DTC, blue sheath/spermatheca precursor cells, light blue sheath nuclei, grey spermatheca, and white uterus. Germline nuclei and their surrounding cytoplasm are often referred to as "germ cells", though they are open to a core of shared cytoplasm (rachis) during much of their development. |
