After the pollen tube enters the gametophyte, the pollen tube nucleus disintegrates and the two sperm cells are released; one of the two sperm cells fertilises the egg cell (at the bottom of the gametophyte near the micropyle), forming a diploid (2n) zygote.
When the fertilized egg attaches itself to the uterine wall and begins to produce hCG it is called implantation. This typically occurs between 6 and 8 days after ovulation. The egg is fertilized in the outer part of the fallopian tube, generally within 12 hours of ovulation.After it is fertilized, the egg travels down the fallopian tube. The fertilized egg grows as it travels. It doubles, the grows to four cells and then to eight cells as it enters the uterus.Implantation occurs in the upper third of the uterus.Implantation sometimes can cause bleeding or minor spotting.fter it is fertilized, the egg travels down the fallopian tube.
