I just want to clarify that Sperm Cell contain X "OR" Y chromosome, not X "and" Y.
What else can I help you with?
How many of the 46 chromosomes are gametes?
Gametes are a specific class of cell, which contains chromosomes. Gametes are not a type of chromosome. Most cells in the human body are "diploid," which means they contain two copies of the 23 chromosomes, for a total of 46 chromosomes. Of those, two are sex chromosomes: classified as X or Y. Gametes, however, are reproductive cells: egg cells in the female, and sperm cells in the male. Gametes are "haploid," which means they only contain one copy of of the 23 chromosomes, and only one sex chromosome (an X in an egg cell, or an X or Y in a sperm cell).
Does the egg sperm determine the gender of a human child?
The sperm. The egg is always an XX chromosome and the sperm can either by XX or XY if the sperm is XX it will be a girl if it is XY it will be a boy.Edit: Actually, all girls have XX chromosomes, and all boys have XY chromosomes. But eggs and sperm are gametes with half the chromosomes of the parents. So all eggs have X chromosomes, and sperm can have either an X or a Y chromosome.(So your intention in the answer was right, but just a small technical error.)
Which sex chromosome do sperm cells carry?
Sperm cells are of two types. One type carries a Y chromosome, while the other type carries an X chromosome. This is the reason why the Spermatid is the 'deciding factor' in whether a baby will be male or female. The Ovum always carries an X chromosome.
Do an egg only have y chromosomes?
No, eggs typically contain one X chromosome. Female reproductive cells (eggs) carry one X chromosome, while male reproductive cells (sperm) can contribute either an X or a Y chromosome. Thus, it is the combination of genetic material from the egg and sperm that determines the genetic sex of offspring.
How many chromosomes are there when a human egg and sperm fuse?
That depends on the species. In the case of humans, egg and sperm cells have half of the chromosomes of a regular cell - 23 chromosomes each. When they join, the resulting cell will have the complete 46 chromosomes.
Which kind of chromosomes are necessary to produce a female?
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.
Does human sperm carry two x chromosomes?
no they only contain a fraction of x chromasomes
How do you become a boy or girl?
Sex is determined by a pair of sex chromosomes. Males have XY chromosomes and females have XX chromosomes. In the fertilization stage where the sperm combines with the egg, the sex of the offspring depends on whether the sperm carries a X or Y chromosome. The ovum always carries a X chromosome because females only have X chromosomes. So, if the sperm carries the X chromosome, the offspring will have XX chromosome and becomes a girl. If it carries the Y, the baby becomes a boy. X (sperm) + X (egg) = XX (female) Y (sperm) + X (egg) = XY (male)
What depends to born a male child in a human being?
The egg has two chromosomes and these are X and X where as a sperm has X and Y chromosomes, when an X form the egg and a Y from the sperm are put together you get a male.
Which chromosomes from the sperm is necessary to produce a male?
x chromosome...!
How many chromosomes in typical human sperm?
23 chromosomes (22 autosomes + Y chromososm or X chromosomes)
Does the sperm determine the gender of a baby?
No. The male determines the sex. A female has 2 X chromosomes, while a man has an X and a Y. A woman can only give an X, but a man can give an X or a Y, thus making the sperm cells the determining factor.
Lifespan of x and y sperm?
There is no such thing as X Y sperm, but there are X/Y Chromosomes. Sperm, once inside the fallopian tube(s) they have a life span of about 5 days. In the vagina, they die in only a few hours. In the open air, they die rapidly.
From man perspective how can he have a male child?
Without laboratory intervention, it's impossible to decide in advance. There's a 50-50 chance. You have both X and a Y chromosomes because you're a guy. Girls have two X chromosomes. Sperm is made up of half of your chromosomes, so half is X and half is Y, and your partner can only be X. So there is a 50-50 chance of getting the XY combination (male).
Why does the dad determine the gender of the baby?
Women have only X chromosomes. Men have one X and one Y. If the man's sperm has an X chromosomes, the child will be a girl. If the man's sperm has a Y chromosome, the child will be a boy.
How do female mammals differ from male mammals in terms of chromosomes?
Female mammals have two X chromosomes in a diploid set and thus only produce homogametes, all of which have only X sex chromosomes. Males produce heterogametes, as they have one X and one Y sex chromosome in a diploid set. Half of a male's sperm cells contain X and half contain Y chromosomes.
Why do some sperm cells have an x chromosome while other sperm cells have a y chromosome?
Chromosomes in adult cells come in pairs. Men's cells have an X Y pair of chromosome in them, women's have two X chromosomes and no Y. When sperm cells are made in the man the sperm get half of each pair of chromosomes and thus half will have the X and half the Y. When a woman makes an egg cell, these to get half her XX pair but all eggs will have an X chromosome. When a baby is made the egg and the sperm join up to give the fertilized egg matched pairs of chromosomes again. As half the sperm carry an X and half a Y, there is a 50% chance that the new egg will be XX (female) or XY (male) and this ensures that there is the same proportion of men and women in the world.
