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.
That would be the Y chromosome. Females are XX, males are XY (with some very rare exceptions. Also, the male's X or Y chromosome will determine the baby's sex.
In humans, which sex chromosome determines if an offspring is a male or female?
The sex of your baby is tottally dependant upon the male's sperm, each sperm has a specific sex chromosome, either a Y or an X . every egg of a female has only X sex chromosomes. When one sperm conjoins with one egg, the female gives her X chromosome and the male gives the chromosome (either X or Y) belonging to the sperm that made it to the egg first and will determine the sex. XX = Female XY = Male * All the things you hear about eating meat during your pregnancy will produce a boy and fruits will produce a girl are myth!
the sperm cell that fertilizes ; y is a boy ; x is a girl
Xy chromosomes= boy xx chromosomes= female
Sex chromosomes are either x or y. The female can only give off xx's, the male however can give x or y. Therefore the male determines the sex of the baby. Its on the 32 chromosome. :)
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.
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.
Sperm is neither male nor female, it is a single cell - the egg determines whether the baby will be male or female.The sperm is the male sex cell, and it has two chromosomes ..... one "X" chromosome and one "Y" chromosome. Females have 2 "X" chromosomes. If the male sperm fertilizes the female egg with an "X" chromosome, the resulting baby will be a girl, but if the male sperm fertilizes the egg with a "Y" chromosome, the resulting baby will be a boy.The male of our species always determines the sex of the child.
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?
Gender is inherited from your parent's 23rd chromosome. The (XX) chromosome pair is for a female and the (XY) chromosome pair is for a male. You get a (X) chromosome from your mother because she has two (x)'s. Her 23rd chromosome is (XX). It's your father's chromosome that determines what gender you are. His 23rd chromosomes were (XY). If you get an (X) from him, you become a girl. If you get a (Y) chromosome from him, you become a boy. This all happens when your mother's egg is fertilized.
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.
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.
In humans, which sex chromosome determines if an offspring is a male or female?
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.
well a persons sex is determined at conception the thing that determines it is the thirty second chromosome whick is provided by a male it can be an X chromosome or a Y chromosome if it is an X the formula is XX (because the women has an X chromosome) and it is a guy if it is XY
