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.
Sperm cells carry either an X or a Y sex chromosome. If a sperm cell carries an X chromosome and fertilizes an egg with an X chromosome, the resulting embryo will be female. If a sperm cell carries a Y chromosome and fertilizes an egg with an X chromosome, the resulting embryo will be male.
The sex Chromosome -number 23- is X X for a Female and X Y for a Male. Whereas all Ovum are X X, that leaves only the sperm to have the deciding role, to contribute either an X or a Y, resulting in either a male or female offspring.
Like all other cell types, chromosomes are found in nucleus only(head of the sperm). But the human sperm cell is haploid, so that its 23 chromosomes can join the 23 chromosomes of the female egg to form a diploid cell during fertilization.

Why is a human cell containing 22 autosomes and a y chromosome a sperm?
A human sperm cell carries half the number of chromosomes as a somatic cell, contributing 22 autosomes and either an X or a Y chromosome. The Y chromosome is essential for determining male characteristics, making the cell a sperm.
Who determines the sex of the baby in humans?
The father determines the sex of the baby in humans. Sperm cells contain either an X or Y chromosome, and the sperm that fertilizes the egg will determine the sex of the baby. If the sperm carries an X chromosome, the baby will be female, and if it carries a Y chromosome, the baby will be male.
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.
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.
What are the sex chromosomes called that do not carry traits?
The sex chromosomes that do not carry traits are called the Y chromosome in males and the second X chromosome in females. These sex chromosomes primarily determine biological sex and are not directly involved in carrying most of the traits that are inherited.
Difference between male and female sperm?
Male sperm (spermatozoa) are smaller, faster, and have a shorter lifespan than female sperm. Male sperm carry the Y chromosome, while female sperm carry the X chromosome. The differences in size, speed, and lifespan contribute to the probability of fertilizing an egg and determining the sex of the resulting embryo.
Which cell contains only one sex chromosome?

How many x and y chromosomes do Normal sperm cells?
Normal sperm cells typically have one X or one Y chromosome, determining the genetic sex of the resulting offspring when the sperm fertilizes an egg.
Why is a human cell containing 22 autosomes and a y chromosome a sperm?
A human sperm cell carries half the number of chromosomes as a somatic cell, contributing 22 autosomes and either an X or a Y chromosome. The Y chromosome is essential for determining male characteristics, making the cell a sperm.
Is there an X or Y chromosome in an egg?
Yes, egg cells contain an X chromosome, while sperm cells can contain either an X or a Y chromosome. The combination of chromosomes from the egg and sperm determines the genetic sex of the offspring.
What sex chromosome does a human egg cell contain?
The sex chromosome typically carried by an ovum is X-chromosome. The sperm may carry either x or y sex chromosome.
Are you more likely to have a boy if the father's family are all boys?
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.
Why does the sperm determine the sex of the offspring not the egg?
The sex of offspring is determined by the sperm because sperm carries either an X or Y chromosome, while eggs always carry an X chromosome. If a sperm carrying an X chromosome fertilizes the egg, it results in a female offspring (XX), while a sperm carrying a Y chromosome leads to a male offspring (XY).
Who determines the sex of the baby in humans?
The father determines the sex of the baby in humans. Sperm cells contain either an X or Y chromosome, and the sperm that fertilizes the egg will determine the sex of the baby. If the sperm carries an X chromosome, the baby will be female, and if it carries a Y chromosome, the baby will be male.
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.
Describe the 3 ways in which the sperm cell and the egg cells differ from each other?
Sperm cells are motile and have a tail for movement, while egg cells are non-motile and stationary. Sperm cells are small and numerous, whereas egg cells are relatively large and limited in number. Sperm cells carry genetic material in the form of either an X or Y chromosome, while egg cells contain only one X chromosome.
Which Forms cells with half the chromosome number of the parent cell?
Sex cells, such as sperm and egg cells, are formed through the process of meiosis, which results in cells with half the chromosome number of the parent cell. This reduction in chromosome number is essential for sexual reproduction and ensures that when the sperm and egg cells combine during fertilization, the resulting zygote will have the normal chromosome number.
