Klinefelter's Syndrome results when a person has XXY chromosomes (an extra X chromosome). The main effects of this are hypogonadism and reduced fertility.
This combination XXY produces a male child with Klinefelter's Syndrome.

Because one of Mr. Smith's sperm, carrying a Y chromosome, fertilized his wife's egg.

It is the sperm from the male determines the sex of the child. Half of the sperms contain the Y chromosome and half the sperms contain the X chromosomes. Ovum from the female always contain the X chromosome. When the sperm with Y chromosome fertilize the ovum, the sex of the child becomes male. When the sperm with X chromosome fertilize the ovum the sex of the child becomes female. The females are wrongly blamed for the birth of female child in some countries.

Everybody has 23 pairs of chromosomes, half they get from their mother and half from their father. The 23rd chromosome you have contains the information of what sex you are. If you are a girl you will have a X chromosome from your mother and and X chromosome from you father. If you are a boy it means you will have a X chromosome from your mother and a Y chromosome from your father. When a sperm cell fertilises an egg the sperm will either be carrying the X chromosome from the male or a Y. If the sperm is carrying a X it will pair with the X chromosome from the mother making the baby a girl. If the sperm is carrying a Y chromosome it will pair with the X chromosome from the mother making the baby a boy! This means it is all down to the father whether the baby is a boy or a girl.
It is the sperm that fertilizes the egg that will determine the sex of your baby. Some sperm carry the X-chromosome and some sperm carry the Y-chromosome. If an X-chromosome-carrying sperm fertilizes the egg, the baby will be a girl. If a Y-chromosome-carrying sperm fertilizes the egg, the baby will be a boy.
Not with another man no. A woman have to be involved somehow by giving them the egg and carrying the baby.Actually yes!Men contain an x chromosome as well. By stem cells an egg cell can be created from a male then fertilized by another man's sperm, implanted in a woman and carried to term.Scientists believe that it would be possible to transfer the genetic material from a sperm cell into an enucleated human egg, and then to fertilize that egg with another sperm cell. There are some technical problems that would have to be overcome, but they may not be insurmountable. One problem would be to insure that if there is a 'male' sperm, carrying the Y chromosome of the XY pair, then the other sperm MUST carry the X chromosome to avoid the possibility of YY offspring. A woman would then receive the fertilized egg and, theoretically, carry it to term.

A male carrying a recessive allele on the X chromosome will exhibit the recessive trait. This is because the Y chromosome generally does not have matching genes for the X chromosome, unlike the other 22 pairs if chromosomes in the nucleus.
Male zygote if it fertilizes the female sex cell, ovum
