How many chromosome pairs are in a sperm duct Cell?
Twenty three.
What is the chromosome carried only by the sperm called?
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.
Is there an X or Y chromosome in an egg?
An egg will have the X chromosome and the sperm will have an X or Y chromosome.
Why does the sperm determine the sex of the offspring not the egg?
The sex of offspring is determined by the sperm because sperm carries either an X or Y chromosome, while eggs always carry an X chromosome. If a sperm carrying an X chromosome fertilizes the egg, it results in a female offspring (XX), while a sperm carrying a Y chromosome leads to a male offspring (XY).
How many genetically different types of sperm cells will result with genes A and B on one chromosome and a and b on the homologous chromosome?
There will be four different genetically different types of sperm cells as a result of the combination of genes A and B on one chromosome and a and b on the homologous chromosome: AB, Ab, aB, and ab.
How many different kind of sperm?
Two, sperm that has an X chromosome and sperm that has a Y chromosome, all things being normal all sperm have the same chromosome count.
If an egg cell contains 50 chromosome how many chromosome are in a sperm cell from the same species?
50
How many chromosome pairs are in a sperm duct Cell?
Twenty three.
How many chromosome are there in gametes?
23 in both Egg Cells and Sperm Cells.
Which chromosome from the sperm is necessary to produce a female?
Y chromosome
Does sperm contain x and y chromosome?
In humans the male sperm contains EITHER an X chromosome, or a Y chromosome since human gametes are haploid (n) in chromosome number.
What is the chromosome carried only by the sperm called?
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.
Is there an X or Y chromosome in an egg?
An egg will have the X chromosome and the sperm will have an X or Y chromosome.
How baby's sex is determined?
The babies sex is determined by the sperm. The egg has XX chromosome and each sperm cell is either a XX or XY chromosome. So which ever sperm cell reaches the egg and implants determines the sex. If the sperm was an XX chromosome the baby would be a girl, if the sperm was XY chromosome the baby will be a boy. Hope this helps!
Are you more likely to have a boy if the father's family are all boys?
It is the sperm that fertilizes the egg that will determine the sex of your baby. Some sperm carry the X-chromosome and some sperm carry the Y-chromosome. If an X-chromosome-carrying sperm fertilizes the egg, the baby will be a girl. If a Y-chromosome-carrying sperm fertilizes the egg, the baby will be a boy.
Is it true that a mans sperm cells determine if a child will be a male or a female?
Yes, it is true that a man's sperm cells determine the sex of a child. Sperm carries either an X or a Y chromosome; if the sperm fertilizes an egg with an X chromosome, the child will be female (XX), and if it fertilizes an egg with a Y chromosome, the child will be male (XY). Therefore, it is the combination of the sperm's chromosome and the egg's chromosome that ultimately determines the child's sex.
What determines if a pregnant women has a male or female?
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.
