ootid

 [o´o-tid]
a mature oocyte (ovum); the cell produced by meiotic division of a secondary oocyte. In mammals, this second maturation division is not completed unless fertilization occurs.

o·o·tid

(ō'ō-tid),
The nearly mature oocyte after the first meiotic division has been completed and the second initiated; in most higher mammals, including humans, the second meiotic division is not completed unless fertilization occurs. Thereafter the ootid contains two separate haploid elements, the female and male pronuclei. When the pronuclei fuse, the ootid becomes a zygote.
[G. ōotidion, a diminutive egg. See -id (2)]
