I am reading the answer and I am getting confused by the sentence:
At the end of meiosis I females have two daughter cells and meiosis II only occurs if and when fertilization occurs by a sperm cell.
The clause suggests me that meiosis II starts after the sperm has ignited the fertilization process in female: I do not know how that exactly works.
The process of fertilization involves a sperm fusing with an ovum.
So female meiosis II must happen before the sperm fuses with the ovum. Sperm must ignite some process in female that puts female meiosis II going on before sperm can fuse with egg. Is that right? How is that going to happen?
