Is there an X or Y chromosome in an egg?
An egg will have the X chromosome and the sperm will have an X or Y chromosome.
How many chromosomes are in a human egg cell?
A human egg cell has 23 chromosomes, which is half the number of chromosomes found in a regular human cell. During fertilization, when the egg merges with a sperm cell, the full complement of 46 chromosomes is restored.
Human cell contains ---------- chromosomes12182646?
All human cells contain 46 chromosomes except for the sperm and egg cells which contain 23 each.
Which cell contains only one sex chromosome?

Does the y chromosome in the male sex cell have a mitochondria?
No, the Y chromosome in the male sex cell (sperm) does not have mitochondria. Mitochondria are inherited from the mother's egg cell, as they contain mitochondrial DNA. The Y chromosome carries genes that determine male sex characteristics.
Why is a human cell containing 22 autosomes and a y chromosome a sperm?
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.
Is there an X or Y chromosome in an egg?
An egg will have the X chromosome and the sperm will have an X or Y chromosome.
What sex chromosome is found in human egg cell?
By human egg cell I guess you mean the oocyte (the one produced by the mother). The oocyte always carries the X chromosome, the sperm can either carry the Y or the X chromosome. Interestingly, the sperm which carries the Y is actually quicker than the one carrying the X, maybe because the X chromosome is far larger. So, if the Y chromosome sperm reaches the egg first, the child will be a boy (XY), and if the X chromosome sperm beats him to it, the child will be a girl (XX).
What percentage of human sperm Cells carry an X chromosome?
50 % of human sperm Cells are an X chromosome, the other half are a Y chromosome: {diploid = 2n = 1 chromosome pair; haploid = n = 1 chromosome - including the meiotic single chromosome = n}. All sperm and egg Cells carry one set each of n (23 single) chromosomes. When a sperm and an egg combine either: a) a sperm Cell with the X chromosome merges with the [X-chromosome] egg Cell and the baby will be a girl; or b) a sperm Cell with the Y chromosome merges with the egg Cell and the baby will be a boy.
If an egg cell contains 50 chromosome how many chromosome are in a sperm cell from the same species?
50
How many chromosomes are in a human egg cell?
A human egg cell has 23 chromosomes, which is half the number of chromosomes found in a regular human cell. During fertilization, when the egg merges with a sperm cell, the full complement of 46 chromosomes is restored.

What is a cell with one-half the regular number of a chromosome?
A sperm cell or an egg cell.
In what type of human cell is the chromosome number 23?
The chromosome number 23 is found in human sex cells, such as eggs (in females) and sperm (in males). These cells are known as haploid cells, containing half the normal number of chromosomes found in somatic cells.
Which cell contains only one sex chromosome?

Female sex cells contain a 1 X chromosome b 2 X chromosomes c 1 Y chromosome or d None of these and why?
All human female egg cells contain X chromosomes, each cell only contains one chromosome. The male sperm cells can contain either an X or a Y chromosome (one or the other, not both). That is what determines the sex of the child, two Xs and its a girl, one x and one y and its a boy. -X
Does the y chromosome in the male sex cell have a mitochondria?
No, the Y chromosome in the male sex cell (sperm) does not have mitochondria. Mitochondria are inherited from the mother's egg cell, as they contain mitochondrial DNA. The Y chromosome carries genes that determine male sex characteristics.
