In Ecuador. As in Chile, Ecuadorian humitas are prepared with fresh ground corn with onions, eggs and spices that vary from region to region, and also by each family's tradition. The dough is wrapped in a corn husk, but is steamed rather than baked or boiled.
Approximately four days after fertilization, the zygote has about 100 cells and is called a blastocyst. When the blastocyst reaches the uterine lining, it floats for about two days and finally implants itself in the uterine wall around six days after fertilization. This signals the beginning of pregnancy.
Fertilization in humans. The sperm and ovum unite through fertilization, creating a zygote that (over the course of 8-9 days) will implant in the uterine wall, where it will reside over the course of 9 months.his is the point when fertilisation actually occurs; pollination and fertilisation are two separate processes. The nucleus of the other sperm cell fuses with two haploid polar nuclei (contained in the central cell) in the centre of the gametophyte.
