yes only one sperm can fertilize one egg.
From smallest to largest: DNA (where DNA = short sequences of nucleotides) gene chromosome nucleus sperm cell
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.
It's determined by the genetic chromosome of the sperm. Women have only one X chromosome in the egg (both egg and sperm have 23 pairs of chromosomes, which unite to form 46). On the other hand, men have either X or Y chromosomes. If an egg (X chromosome) joins with an X chromosome sperm, the result will be a girl. If an egg (X chromosome) joins with a Y chromosome sperm, the result will be a boy. In other words: the guy determines the sex of a baby :)
Human somatic (body) cells contain two sets of 23 chromosomes. Human gametes (sperm and egg cells) contain one set of 23 chromomes -- 22 autosomes and 1 sex chromosome. Only a sperm cell can carry a y chromosome. A sperm cell can also carry an x chromosome. The ovum can carry only an x chromosome, never a y chromosome. So a cell containing 22 autosomes and a y chromosome must be a sperm cell.
Sperm or spermatozoa
yes only one sperm can fertilize one egg.
The sperm can have either X or Y sex chromosome. If the sperm with X chromosome fertilize the ovum, you get female baby. If the sperm with Y chromosome fertilize the ovum, you get male baby. Ovum always has got X chromosome in it.
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
Yes, he must in order to fertilize eggs.
one
Two, sperm that has an X chromosome and sperm that has a Y chromosome, all things being normal all sperm have the same chromosome count.

In humans the sex of the offspring is determined by which sperm is able to fertilize the ovum. If a sperm containing the X chromosome fertilizes the ovum, a female offspring results. If a sperm containing the Y chromosome fertilizes the ovum, a male offspring results

a man can release millions of sperm at once,however only one sperm can fertilize an 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.
no,sigle men single sperm fertilize fimale egg.
