X Chromosome is the congenital, developmental as well as genetic information in the cell, which transmits the necessary information for making a female. All eggs, which contain one X chromosome in them and half of all sperm, which carry X chromosome are to combine in order for a girl would arrive.
Y
Y Chromosome is the congenital, developmental as well as genetic information in the cell, which transmits the necessary information for making a male. The Y chromosome may possibly be found in one – half of the man’s sperm cells. When an X and a Y chromosome get together, the baby will become a boy.
Z
ZIFT (Zygote Intrafallopian Transfer) is an ART, where the eggs are removed from the ovaries of a woman, fertilized with her husband’s / male partner’s sperm in a special lab dish, and the embryo, which becomes the result of this fertilization, is then moved into the woman’s Fallopian Tubes with the help of a minor surgical procedure.
Zona Pellucida is called a protein membrane, which surrounds and provides protection for the oocyte. As a rule in about five days after the fertilization takes place, the zona pellucida breaks down in order to let the embryo to continue its development.
Zygote is a conceptus, in which the genetic material of an egg and sperm gets united.
