What is the sex chromosome in man?
For mammals, sperm.
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.
Is it true that a mans sperm cells determine if a child will be a male or a female?
Yes, it is true that a man's sperm cells determine the sex of a child. Sperm carries either an X or a Y chromosome; if the sperm fertilizes an egg with an X chromosome, the child will be female (XX), and if it fertilizes an egg with a Y chromosome, the child will be male (XY). Therefore, it is the combination of the sperm's chromosome and the egg's chromosome that ultimately determines the child's sex.
Does a mans sperm always have the same chromosomes?
Man is always the Y chromosome.
Does the man play a role in determining the gender of the baby"?
Yes, the man's sperm determines the gender of the baby through the presence of either an X or Y chromosome.
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.
Are the functions of the testes?
To create Testosterone, which basically makes a man like a man, and sperm, to reproduce.
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 many chromosomes does an orangutan sperm cell have?
The diploid chromosome number for the orangutan is 48 (two more than man), so an orangutan sperm cell would contain 24 chromosomes.
Is the man or woman responsible in detetming the sex of a baby?
The man is responsible for determining the sex of a baby. Sperm carries either an X or Y chromosome, which determines the baby's sex when it fertilizes the egg. If an X-carrying sperm fertilizes the egg, it will be a girl (XX); if a Y-carrying sperm fertilizes the egg, it will be a boy (XY).
Can a man have only x or y chromosomes in his sperm?
Yes, all male have sperm cell contain both a X and Y chromosome and female have only two Y chromosomeI just want to clarify that Sperm Cell contain X "OR" Y chromosome, not X "and" Y.
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.
