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 happinds of a child receives an X chromosome from its mother and a Y chromosome from its father .?
The child is a biological male.
Why does every child get a unique set of chromosomes?
Because of the process of crossing over that occurs during prophase I, and also because the child inherits half of its chromosomes from its mother and half from its father.
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.
How are the humans sex chromosomes labeled?
Answer We label the human sex chromosomes with X's and Y's. For example. A boy's chromosomes are XY. A girls chromosomes are XX. When a child is born, they get an X from their mother, and either an X or Y from their Father, thus determining their sex.
A child receives an X chromosome from it’s mother and a Y chromosome from it’s father. What is true about this child?
it is male

The child is a biological male.
How is it possible that a child inherits equally from its mother and father?
If the egg and sperm have the same amount of chromosomes.

How many chromosomes does the father give to a baby?
A mother and a father both give the child an even number from each, which would be 23 each.
How many chromosomes do both your mom and dad give a child?
Exactly half of all chromosomes come from mother. The other half comes from father. This is true for ALL species that sexually reproduce.
Who would you consider more of a biological brother and sister children that are born from the same mother different father or children from the same father different mother?
Since the father and mother each contribute half (23 chromosomes) of the genetic material needed to form a child (46 chromosomes), the brother and sister are equal in terms of biological similarity, no matter if they had a different mother (same father) or father (same mother). However, if any of the father/mother pairs are related, the result is skewed.
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.
How does the number of chromosomes in sex cells compared with the number of chromosomes in body cells?
Sex cells have 23 chromosomes compared to the body cells' 46 chromosomes. This is because a child is created from half the genome of its father and half the genome of its mother. In other words, 23 chromosomes in the mother's egg and 23 chromosomes in the father's sperm, when combined generate a child with 46 chromosomes in its body cells. However, sometimes mutations occur where more of fewer chromosomes are passed down, this will either result in no embryotic development or the embryo having some kind of syndrome.
