How does the father determine the gender of a child?
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.
What is the chance that a human zygote will receive one x and one y sex chromosomes during fertilization?
The chance is 50%.
Why does the father ultimately determine thesex if the baby?
The father's contribution to the baby's sex determination is through the sperm, which carries either an X (female) or Y (male) chromosome. The mother's egg always carries an X chromosome. When a sperm carrying a Y chromosome fertilizes the egg, the baby will be male; when a sperm carrying an X chromosome fertilizes the egg, the baby will be female.
Whose chromosomes determine the sex of offspring in humans?
The males chromosomes determine the gender of the baby. Women have an XX chromosome and men have an XY chromosome. So women can only give an X chromosome, but men can give either/or.The chromosomes of the father make the final determination; the child either gets a X from the mother and either an X from the father which makes a girl, or an X from the mother and a Y from the father, which makes a boy.Jamiana:The Father's(it's Y though)
Explain how the type of chromosome results in some children being male and others being female?
A child's gender is dependent on which chromosome (X or Y) is received from the father. The mother has the chromosomes XX and the father has XY. Each parent randomly gives the child one of their respective chromosomes (through meiosis). The mother gives one of her two X chromosomes and the father gives either the X or the Y. If the father gives a copy of his X chromosome, the baby is a girl. If the father gives his Y chromosome, the baby is a boy.
Why is the y chromosome useful for tracing ancestry?
The y-chromosome is only present in males. Men will a y-chromosome identical to that of their father, and his father, and his father, etc.
What is y-chromosoze?
Y chromosome is the 2nd chromosome in a male homolouge it has the contribution in sex determination of the embryo.
How does the father determine the gender of a child?

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.

Which sex chromosome does a father pass on to a son?
A father passes on his Y chromosome to his son. In humans, males have one X and one Y chromosome (XY), while females have two X chromosomes (XX). Therefore, the son inherits the Y chromosome from his father and an X chromosome from his mother, resulting in a male (XY) offspring.
Why does the father ultimately determine thesex if the baby?
The father's contribution to the baby's sex determination is through the sperm, which carries either an X (female) or Y (male) chromosome. The mother's egg always carries an X chromosome. When a sperm carrying a Y chromosome fertilizes the egg, the baby will be male; when a sperm carrying an X chromosome fertilizes the egg, the baby will be female.
What sex chromosome does a girl obtain from her father?
Both parents will give a girl an X chromosome. The father will give a Y and the mother will give an X to a boy.
Can a male have the same X chromosome as his paternal grandfather?
No, he cannot.He cannot even have the same X chromosome as his father.The reason is that a male has an X and a Y chromosome in his genome. The Y must come from Dad, because Mum does not have any Y to pass on!So the X must come from Mum.Now looking at grandparents: a male's father supplied the Y, and father's Y came from the paternal grandfather. So the paternal grandfather's contribution must be the Y chromosome.The male's Mum has two X chromosomes, one from the maternal grandfather, and one from Mum's Mum.
Which parents gamete normally determines the sex of the child?
The father's gamete determines the sex of the child. Specifically, the presence or absence of a Y chromosome in the father's sperm will determine if the child will be male (Y chromosome present) or female (no Y chromosome).
Whose chromosomes determine the sex of offspring in humans?
The males chromosomes determine the gender of the baby. Women have an XX chromosome and men have an XY chromosome. So women can only give an X chromosome, but men can give either/or.The chromosomes of the father make the final determination; the child either gets a X from the mother and either an X from the father which makes a girl, or an X from the mother and a Y from the father, which makes a boy.Jamiana:The Father's(it's Y though)
Y linked genes are passed only from who?
Y-linked genes are only passed from father to son because the Y chromosome is inherited exclusively in a paternal manner. Since females inherit an X chromosome from each parent, they do not receive a Y chromosome from their father.
If a trait is always transmitted directly from a father to all his sons and from those sons to all their son what chromosome would the gene for the character be likely on?
The gene for this trait is likely located on the Y chromosome. The Y chromosome is passed down from father to son, and since only males have a Y chromosome, the trait will only be passed down through male lineage.
