What chromosomes determine a person gender?
Xy chromosomes= boy xx chromosomes= female
Which kind of chromosomes are necessary to produce a female?
There are two types of chromosome, called X and Y. Semen contains X sperm and Y sperm. If the Y sperm fertilises the female ovum, the child will be male. If the X sperm fertilises the female ovum, the child will be female. A man's chromosomes will be XY and a woman's chromosomes will be XX. The man's sperm always determines the gender of the baby.
Is sperm male or female?
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.
Do you have a explanation about being a baby boy or girl?
Female humans have two X chromosomes, males have one X and on Y. The female contributes one X to the child. The male contributes either an X or a Y. This determines the sex of the child. If the sperm carries a Y chromosome, the child will be male, if the sperm carries an X chromosome the child will be female.
Can a mother pass on a y chromosome to its child?
No. If it is a mother, that infers that the organism is female. The feature that determines gender is the 23rd set of chromosomes. A female can only result if the pair is XX (XY results in a male). Therefore, a mother cannot pass on a Y chromosome to her child. If you are wondering whether by cause of a genetic mutation the mother happens to have a Y chromosome, then she would not be a mother, as she would be infertile.
When is the baby sex determined?
It is the sperm from the male determines the sex of the child. Half of the sperms contain the Y chromosome and half the sperms contain the X chromosomes. Ovum from the female always contain the X chromosome. When the sperm with Y chromosome fertilize the ovum, the sex of the child becomes male. When the sperm with X chromosome fertilize the ovum the sex of the child becomes female. The females are wrongly blamed for the birth of female child in some countries.
How many chromosomes do the parents of a child with Down syndrome have?
