Genetically speaking, the gender of a baby is determined by the presence of the 'Y' chromosome (or the absence of it).
If a Punnett square were to be drawn and a mono-hybrid cross carried out, you can see that the only chromosome the female (XX) can pass on is the X chromosome. The male (XY) can pass on either his 'X' or his 'Y'.
If the male passes on his X chromosome, the two chromosomes fuse to form XX, therefore becoming female. But if the male passes on his Y chromosome, XY is formed which is a male. Hence, the male always determines the gender of an offspring.
The chromosome carried only by the sperm is called the Y chromosome, which determines the male gender when combined with the X chromosome from the egg during fertilization.
The sperm gamete determines the gender of the offspring in humans. Sperm carries either an X or a Y sex chromosome, while the egg always contains an X chromosome. If a sperm with an X chromosome fertilizes the egg, the offspring will be female (XX). If a sperm with a Y chromosome fertilizes the egg, the offspring will be male (XY).
The sex of a baby is determined by the chromosomes carried by the father's sperm. If the sperm carries an X chromosome, the baby will be female, and if it carries a Y chromosome, the baby will be male.
In humans, which sex chromosome determines if an offspring is a male or female?
the sperm cell that fertilizes ; y is a boy ; x is a girl
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.
The gender of a baby is determined by the father's sperm at the moment of fertilization. Sperm cells carry either an X or a Y chromosome, and the combination of chromosomes from the sperm and egg determines the baby's gender. If a sperm carrying an X chromosome fertilizes the egg, the baby will be female (XX); if a sperm carrying a Y chromosome fertilizes the egg, the baby will be male (XY).
Yes. Sperm carry either an X or a Y chromosome. The eggs from a female's ovaries is always X. If the sperm has an X chromosome, the baby will be female. If the sperm has a Y chromosome, the baby will be male.
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.
I will explain, but I don't know why you put this in cat behavior. The X chromosome and Y chromosome control gender. If an embryo's two chromosomes are XX, it will be a girl. If the chromosomes are XY, it will be male. A pair of chromosomes have to have at least one X chromosome in it, but can also have a Y chromosome.
A male typically has one X chromosome and one Y chromosome, which determines his biological sex as male.
The chromosome carried only by the sperm is called the Y chromosome, which determines the male gender when combined with the X chromosome from the egg during fertilization.
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 sperm can have either X or Y sex chromosome. If the sperm with X chromosome fertilize the ovum, you get female baby. If the sperm with Y chromosome fertilize the ovum, you get male baby. Ovum always has got X chromosome in it.
In humans, which sex chromosome determines if an offspring is a male or female?
The sperm gamete determines the gender of the offspring in humans. Sperm carries either an X or a Y sex chromosome, while the egg always contains an X chromosome. If a sperm with an X chromosome fertilizes the egg, the offspring will be female (XX). If a sperm with a Y chromosome fertilizes the egg, the offspring will be male (XY).
No. The male determines the sex. A female has 2 X chromosomes, while a man has an X and a Y. A woman can only give an X, but a man can give an X or a Y, thus making the sperm cells the determining factor.
