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.
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.
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.
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.
Why 'y' chromosomes are obsolete nowadays?
They are not obsolete. Y chromosomes are what make males. When a child is conceived, they get two chromosomes: one from their mother, and one from their father. Since all women have two X chromosomes, the child gets an X from their mother. The father can give the child either an X or Y chromosome depending on the sperm that fertilizes the egg, since men have one X chromosome and one Y chromosome.
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.
Does a mothers chromosome determine a childs sex?
the males X and Y chromosomes and the females X chromosomes
Does a mother that doesn't work but receives money from oil and gas leases and a father that receives ssi have to pay child support if they signed custody of children over to family?
her yes, him no.
What chromosome has to be present for a mother to have a male child?
Y chromosome
Your niece lives with you but her mother receives child support how can your niece receive it instead?
