How many chromosomes in typical human sperm?
23 chromosomes (22 autosomes + Y chromososm or X chromosomes)
A skin cell has how many chromosomes?
A human skin cell has 46 chromosomes. A sperm has 23, and an egg has 23. When put together it completes the 46 needed to start making you :) x
What are the different types of sex cells?
The human gametes are the sperm cell (male) and the egg cell (female). The chromosomes carried by the sperm cell can have two forms, the X cell (female offspring) or the Y cell (male offspring). These combine with the egg cell, which virtually always carries only an X chromosome. So an XX cell would develop as a female, and an XY cell would result in a male offspring.
What cell type could have 22 chromosomes and a Y chromosome?
The cell type that has 22 autosomes and an X sex chromosome is a gamete, such as an egg or sperm cell.
What chromosomes make a boy or a girl?
It is because males produce sperm cells with the X chromosome and sperm cells with the Y chromosome. If a sperm cell with a Y chromosome fertilizes an egg, then that child would be a boy, as the Y chromosome produces male offspring. If a sperm cell with a X chromosome fertilizes an egg, then the child would be a girl, as X is the female chromosome. The mother always passes on a X chromosome, but the father can pass on an X or a Y and thus determine the sex of the baby.
How many chromosomes in typical human sperm?
23 chromosomes (22 autosomes + Y chromososm or X chromosomes)
What makes sperm?
Well, to start of you gotta know what chromosomes are, that are x shaped bundels of DNA that cointain gens. In every human cell there are 46 chromosomes. A sperm has 23 of them. When a cell starts reproducing, it doubles It's amount of chromosomes so when it splits, both have 46 chromosomes and thats a normal cell, BUT when creating sperm the cells split AGAIN an then they have 4 sperm cells and each has 23 chromosomes.
How many chromosomes do frogs have in its gametes?
Frogs have 26 chromosomes in their somatic cells. A frog's sperm would be a haploid cell, meaning that the cell contains half the amount of chromosomes that it's somatic cells have. So a frog's sperm cell would contain 13 chromosomes.
How many chromosomes are in a sperm cell and in an egg cell?
Each gamete (or egg/sperm cell) has 23 chromosomes. So both egg & sperm cells have 23 chromosomes, however because gametes undergo meiosis the chromosomes are haploids so they don't look like X's. So they are not actually in pairs, as just eggs & sperm. They pair up once an egg is fertilized.

Human cell containing 22 autosomes and a Y chromosome?
A normal human cell containing 44 autosomes and two X chromosomes is a somatic cell of a female. The word "somatic" comes from the Greek word "soma" which means body.
What chromosomes make a boy or a girl?
It is because males produce sperm cells with the X chromosome and sperm cells with the Y chromosome. If a sperm cell with a Y chromosome fertilizes an egg, then that child would be a boy, as the Y chromosome produces male offspring. If a sperm cell with a X chromosome fertilizes an egg, then the child would be a girl, as X is the female chromosome. The mother always passes on a X chromosome, but the father can pass on an X or a Y and thus determine the sex of the baby.
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.
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.
What percent of human sperm Cells carry a pair of X chromosomes?
Human sperm does have chromosomes, in fact it has 23 of them, but they are not paired. The human sperm is a haploid cell meaning that it contains half of the chromosomes of most other cells (23), while most of the other cells of the body are diploid cells which contain 46 chromosomes. Sex is determined by the combination of the X chromosome donated by the mother, and either the X or the Y donated by the father. XX makes a girl, while XY makes a boy. While the egg normally always contains an X chromosome, and the sperm can have either an X or a Y chromosome, neither the sperm, nor the egg contain "a pair" of X chromosomes.
