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 shape do chromosomes resemble?
If you mean as a whole, most chromosomes resemble the shape of the letter X. There may be a sex chromosome, and it may resemble the letter V in males of the species, though in that case, it is called a Y-Chromosome. During the anaphase of mitosis, they would be L-shaped.If you mean in terms of the shape of the genetic material, then chromosomes have a double-helix shape.
What is the shape of chromosome in human body?
All 23 pairs of chromosomes are in the shape of an X, except for the Y chromosome, of which one is found in the nucleus of each male cell. This one is (surprise, surprise) in the shape of a Y. If you look at a human female cell, all 23 pairs are comprised entirely of X-shaped chromosomes.
Who has the sex chromosome?
Every mammal (of any species, including human) have two sex chromosomes, which are either "X" or "Y". (These designations come from a vague approximation of the shape of the chromosome.) These exist in EVERY CELL in the animal. If the animal has two "X" chromosomes, the animal is female; if the animal has one "X" and one "Y" chromosome, the animal is male. In every species, the female only contributes an "X" chromosome to the offspring. It is the male contribution which might be either "X" or "Y", which will determine the gender of the child.

Why is x chromosome called x?

An x chromosome is specifically a feminine chromosome. With a x and y chromosome its male, with a x and x, it is a female.
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.
Does an x chromosome looks the same as a y chromosome?
No. An 'X' chromosome looks like an 'X'. The 'Y' chromosome looks like a deformed 'X'. It is noticeably different to an 'X' chromosome. Also, the 'Y' chromosome is only a third of the size of an 'X' chromosome - an 'X' chromosome is 155 million base pares, while the 'Y' chromosome is only 58 million base pairs.

What sex chromosome is present in all humans?
There are two sex chromosomes: the X chromosome and the Y chromosome. During fertilization, the mother always gives an X chromosome and the father gives either another X chromosome or a Y chromosome. Therefore, all humans have at least one X chromosome.
What does it means when the X Chromosome is higher than the Y Chromosome?
The X chromosome is stood on a yellow pages
