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 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!
In humans, which sex chromosome determines if an offspring is a male or female?
The type of chromosome that determines gender is called a sex chromosome. In humans, there are two sex chromosomes: X and Y. Typically, individuals with two X chromosomes (XX) are female, while those with one X and one Y chromosome (XY) are male. The presence of the Y chromosome triggers male sex development, while the absence of it leads to female development.
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).
The father determines the gender of a child through the contribution of his sperm during fertilization. Sperm carries either an X or Y chromosome, which combines with the mother's X chromosome to determine the baby's gender. If the sperm carries an X chromosome, the baby will be female, and if it carries a Y chromosome, the baby will be male.
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.
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.
Males contribute to determining the gender of a baby through the sperm they provide during fertilization. Sperm carries either an X or Y chromosome, which combines with the X chromosome from the female's egg to determine the baby's gender. If the sperm carries an X chromosome, the baby will be female, and if it carries a Y chromosome, the baby will be male.
Testosterone levels do not directly impact the gender of a baby. The gender of a baby is determined by the chromosomes inherited from the parents. Specifically, the presence of a Y chromosome from the father will result in a male baby, while the absence of a Y chromosome will result in a female baby. Testosterone levels may influence the development of male characteristics in a baby after conception, but they do not determine the baby's gender.
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.
