it is male

What happinds of a child receives an X chromosome from its mother and a Y chromosome from its father .?
The child is a biological male.
A child will be a girl if she receives what chromosomes from father and what chromosomes from mother?
A child's sex is actually determined entirely by his or her father. All eggs in a woman's body contain and X chromosome, whereas sperm cells contain either X or Y. The female sex chromosomes are XX and the male sex chromosomes are XY. Thus, if the sperm that fertilizes the egg contains an X chromosome, the child will be a girl. If the sperm contains a Y chromosome, the child will be a boy.
What chromosome has to be present for a mother to have a male child?
A mother needs to contribute an X chromosome to her child for them to be male. The father contributes a Y chromosome, resulting in an XY chromosome pair which determines a male child.
Does the father determine the gender of the child"?
No, the father's sperm carries either an X or Y chromosome, but it is the mother's egg that ultimately determines the gender of the child. If the egg is fertilized by a sperm with an X chromosome, the child will be female, and if it is fertilized by a sperm with a Y chromosome, the child will be male.
Which gamete determines the gender of the young?
In humans females are homogametic and males are heterogametic. It is the male biological parent who contributes the sex chromosome that determines the sex of any child.Human females are XX and all their ova carry an X chromosome. Females always give their children an X chromosome.Human males are XY and half their spermatozoa carry an X chromosome and half carry a Y chromosome. Depending on the sex chromosome in its biological father's spermatozoon, a child receives an X or a Y chromosome from its biological father.If a child receives an X chromosome from its father she will be XX and a girl. If a child receives a Y chromosome from its father he will be XY and a boy.
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.
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.
Does a mothers chromosome determine a childs sex?
the males X and Y chromosomes and the females X chromosomes
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.
Is the mitochondrial DNA in a baby more like the mitochondrial DNA from his mother's mother or the mitochondrial DNA from his father's mother?
It is exactly like the mothers (except for some possible random mutations). The mother's egg has all of the cytoplasmic components inside it. The sperm only carries DNA. So mitochondria are maternally inherited. While the sperm does contain mitochondria in its tail, only the DNA from the head are transported into the ovum. The DNA of the child consists of half the genetics of the mother and half the genetics of the father. This is because the sperm carries 22 chromosomes and an extra sex chromosome (X or Y). The egg inside the mother also carries 22 chromosomes and a sex chromosome (X or X). When these meet we get 22 sets of chromosomes and a set of sex chromosome (X,Y or X,X) which determines the gender of the child. However, if the mother or the father is carrying an extra 21st chromosome and for example, the child receives 2 21st chromosomes from the father and 1 from the mother, they now have 3 21st chromosomes which can lead to the child being born with downs syndrome.
If a mom colorblind and the father not colorblind what is the probability the child will be colorblind?
If the mother is a carrier of the colorblind gene (XcX) and the father has normal color vision, the probability of their child being colorblind is 50%. This is because the child has a 50% chance of inheriting the Xc chromosome from the mother and developing colorblindness.
Does the egg determine the sex of a child?
No, the egg is from the mother and can only carry the X chromosome (since the mother is XX). The sperm will be either X or Y (since the father is XY), and will determine the sex of the child.
