The sperm must have an X chromosome as opposed to a Y chromosome.
X Chromosome results in a female Y Chromosome results in a male All sperm are either going to be an X or Y chromosome All eggs are X chromosome only
There are two types of chromosome, called X and Y. Semen contains X sperm and Y sperm. If the Y sperm fertilises the female ovum, the child will be male. If the X sperm fertilises the female ovum, the child will be female. A man's chromosomes will be XY and a woman's chromosomes will be XX. The man's sperm always determines the gender of the baby.
How long sperm can survive in the female body depends on how healthy the sperm are and whether the female is fertile at the time. If there is fertile quality cervical mucus present then sperm can potential survive for up to a week within her body.
Fertile eggs in humans die naturally if they are not?æfertilized by sperm. The human female's ovulation cycle is 28 days long.?æ
The sperm which has got X chromosome in it. Fortunately it is not possible to isolate such types of sperms. It will be better that you do not have the technology to determine the sex of the child by way of selecting the sperms. Technology have already disturbed the sex ratio is some countries of the world.
A male would have to deposit his sperm within the female's reproductive tract during the same time that the female releases a fertile egg from her ovary.
Yes, definately. In some cases, when a couple wants a child, the male cannot ejaculate sperm. As such, there are donors of sperm. The sperm is just put in the female reproductive organ and the female falls pregnant

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.
Sperm can typically survive in the female reproductive tract for up to 5 days. It is highly unlikely for sperm to survive for 3 months inside a female and still result in a pregnancy.
Female humans have two X chromosomes, males have one X and on Y. The female contributes one X to the child. The male contributes either an X or a Y. This determines the sex of the child. If the sperm carries a Y chromosome, the child will be male, if the sperm carries an X chromosome the child will be female.
Because male has sperm cell while female has ovum cell
