What sperm must fertilize an egg to result a female child?
If a sperm with an X chromosome fertilizes the egg, the new cell will have two X chromosomes. One came from the father’s sperm and one came from the mother’s egg. Since the sex chromosome that is made is XX, the cell will grow into a girl baby.
What process immediately follows fertilization of the egg?
Formation of the fertilization membrane The most spectacular changes that follow fertilization occur at the egg surface. An immediate response to fertilization is the raising of a membrane, called a vitelline membrane, from the egg surface.
Where does the process of fertilization take place?
Human fertilization is defined as the union between egg and sperm cells to cause a pregnancy. In humans, fertilization is an internal process, which is to say, it takes place inside the body of females, particularly in the Fallopian tubes, hence the more specific term natural or ‘in vivo’…
What is the definition of fertilization in humans?

How does the fertilization process affect the gender of the baby?
The fertilization process of humans culminates with the formation of the zygote: the first cell of the organism, created after egg and sperm fuse into one. In addition to all this, fertilization determines the gender of the baby-to-be based on sex chromosomes:
Which is true about the fusion of sperm and egg?
8. Fertilization is defined as the fusion between the male and female gametes, that is, sperm and egg, thereby reestablishing the normal number of chromosomes in humans (46 chromosomes). For human fertilization to be possible, it is necessary that a man ejaculates inside the vagina of a woman.
