Zygote intrafallopian transfer (ZIFT) is similar to in vitro fertilization (IVF) and GIFT, but in this procedure eggs are fertilized in a lab before a doctor places them inside your fallopian tubes. When a sperm cell penetrates and fertilizes an egg, that genetic information combines. is due to heredity and environment each affecting the other.

Bones, muscles, skin, and connective tissues form. The sperm and the egg are gametes.
The zygote divides to become a ball of cells that eventually implants in the wall of the uterus. From week 10 of pregnancy, the fetus grows inside the uterus, fueled by nutrient-rich blood supplied by the umbilical cord.
The baby has the ability to make a fist and its eyes remain closed now until the opening after the 28th week of development, MedlinePlus reports.

The embryo grows and becomes surrounded by structures that provide support and nourishment. The baby's head moves through the birth canal. Why it's done. As it travels toward the uterus it divides to become a blastocyst, which will burrow into the uterine wall.
