Why is chromosome analysis recommended for gender test of a child?

That is just a good starting point. If you don't know what sex someone was supposed to be, then karyotyping can be a good place to start. It can also give a clue as to what underlying conditions there might be. For instance XY chromosomes and natural feminine features could indicate androgen insensitivity syndrome. On the other hand, androgynous features and an extra sex chromosome would indicate Kleinfelter's syndrome.

Is it true or false that the 23rd chromosome pair determines the gender of a child?
TRUE.
What determines the gender of children?
the sperm cell that fertilizes ; y is a boy ; x is a girl
You already have a son will you fall pregnant with a girl next?
There is no way to predict what the gender of your next child is- it just depends on whether the sperm carries the x chromosome or the y chromosome.
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.
Which sex cell controls the sex of a baby?
I will explain, but I don't know why you put this in cat behavior. The X chromosome and Y chromosome control gender. If an embryo's two chromosomes are XX, it will be a girl. If the chromosomes are XY, it will be male. A pair of chromosomes have to have at least one X chromosome in it, but can also have a Y chromosome.
How do you know whether the chromosome passed from father is Y or X?
The sex of an individual is determined by the combination of sex chromosomes received from their parents. Typically, females have two X chromosomes (XX) and males have one X and one Y chromosome (XY). To determine whether the chromosome passed from the father is Y or X, the presence of a Y chromosome can be identified through genetic tests, such as a karyotype analysis or DNA sequencing.
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.
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
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.
If a male donates a Y chromosome and the female donates an X chromosome what is the sex of the child?
We are learning new theories of gender/sexual preference every day as a result of more advanced studies. Until recently, however, it was generally accepted that a sperm with a y chromosome would produce a male child and a sperm with an x chromosome would produce a female child. Biologists have discovered that things may no longer be quite that simple in some cases. For example, traditional wisdom says that boys have an X and Y chromosome pair and that girls have an X and X pair. They have learned that in cases of gender identity, some men are born with an extra X, sometimes even two extra Xs. In such a scenario, their gender chromosomal makeup can be XXXY, weakening the Y (male) sequence enough to cause gender confusion. The same is true of girls. Sometimes, they are born with only one X in the chromosomal pair which can result in more masculine traits. But until these studies are more broadly accepted, it is fairly safe to say, that the Y half of a chromosome pair will result in a male offspring.
What kind of chromosomes do females transmit to offspring?
Female transmit 23 chromosomes to the offspring. She has that unique chromosome called as X chromosome. This is transmitted to the offspring. From male you get either X or Y chromosome. From XX chromosome you get female child. From XY chromosome you get male child.
What has alleles that are passed parent to child on a sex chromosome?
Sex-linked traits have alleles that are passed from parent to child on a sex chromosome.
