The sex of a baby at fertilization is determined by the chromosomes the baby possesses. If these chromosomes are XY it's a boy. If they are XX, it's a girl.
http://en.wikipedia.org/wiki/XY_sex-determination_system
The father determines the sex of the baby in humans. Sperm cells contain either an X or Y chromosome, and the sperm that fertilizes the egg will determine the sex of the baby. If the sperm carries an X chromosome, the baby will be female, and if it carries a Y chromosome, the baby will be male.
there is a baby
The male sex chromosome is XY, and females are XX. The X comes from the female, and an X or a Y from the male. When they meet, that determines whether the baby will be a boy or a girl.
The female sex cell, also known as the egg or ovum, produces half of the genetic material needed for reproduction. During fertilization, the egg combines with a male sex cell (sperm) to form a complete set of chromosomes for a new individual.
The sperm from the father can supply either an X-bearing or a Y-bearing chromosome. The egg from the mother can only supply an X-bearing chromosome. An XY combination produces a boy baby. An XX combination produces a girl baby. It might seem that the father therefore determines the sex of the baby, but some recent evidence suggests that the mother can select either an X-bearing or a Y-bearing sperm. See the Wikipedia article on "Maternal influence on sex determination."
I had sex with justin bieber and now i have a baby boy
I believe the father of the baby determines the sex of the baby.
The father determines the sex of the baby in humans. Sperm cells contain either an X or Y chromosome, and the sperm that fertilizes the egg will determine the sex of the baby. If the sperm carries an X chromosome, the baby will be female, and if it carries a Y chromosome, the baby will be male.
The chromosome in the male's gamete determines the gender of the baby. If it is a Y chromosome, the baby will be a boy. If the chromosome is a X, the baby will be a girl.
Yes, the male determines the sex of a baby. He possesses the either X or Y chromosome. The X is a girl I believe & the Y is a boy, I'm pretty sure that that's what they stand for. I'm positive that the male determines the sex of a baby though.
No, it is the sperm that determines the sex of the baby. Sperm carry either an X or a Y chromosome, and when one of them fertilizes the egg, the resulting combination will determine the baby's sex (XX for female, XY for male).
NO
Well, there is fertilization in sexual reproduction, but there is not fertilization in asexual because the female reproductive system needs help with the male reproductive system through sex. Without sex, it is asexual. Females need the males sperm in order to fertilize the baby or plant.
the answer is sex chromosomes
I believe you meant to ask is it possible to know the sex of a baby conceived by inviro fertilization also called test tube baby. Of course like a normal baby a test tube baby too has xx or xy chromosomes and the sex can be determined actively while the fetus is growing. Also like a normal baby ultrasonograph can reveal the sex of the child.
In order to physically have a baby, a man would need female hormones, at least one of two functioning ovaries to produce eggs, a uterus for the egg to implant, and a means of fertilization (i.e. sex with a male or medically assisted fertilization).
Im assuming you mean "Do pandas have to have sex to make a baby?" In most cases yes, however, there is a procedure known as "In Vitro Fertilization", in which an egg is fertilized in a lab, and implanted into the womb. This makes it possible to become pregnant without having sex.
