In terms of base pairs, the X chromosome is about 155 megabases (million bases), and the Y is about 57 megabases.
Note that there can be variation in the lengths of Y chromosomes between men, due to different amounts of constitutive heterochromatin on the long arm. That is, the long arm of the Y contains repeated sequences. The number of these sequences can be different between individuals, thus the size of the chromosome can be different between men.

What is bigger E. coil bacteria or an X chromosome?
bacteria
Why does the y chromosome not carry any alleles?
The Y chromosome is smaller than the X chromosome and contains fewer genes. It carries the genes necessary for determining male sex and some other genes, but it lacks many of the genes present on the X chromosome. This is why the Y chromosome does not carry any alleles in the same way that the X chromosome does.
Can you live with a y-chromosome and no x-chromosome?
No. The human X chromosome contains over 1000 genes, many of which are essential for life. The Y chromosome in comparison has only about 120 genes. A zygote with Y0 or YY (one or two Y chromosomes) would not be viable.
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 chromosome is the triple x syndrome found on?
Triple X syndrome, also known as 47,XXX, is a genetic condition caused by the presence of an extra X chromosome in females. This condition occurs due to nondisjunction during meiosis, resulting in a total of three X chromosomes instead of the typical two. It is associated with various physical and developmental features, but many individuals may have mild symptoms or none at all. The extra X chromosome is located on the X chromosome itself, so it is not associated with a specific chromosome number other than the X chromosome.
What is bigger E. coil bacteria or an X chromosome?
bacteria
Is an x chromosome and chromosome the same thing?
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.
Why is x chromosome called x?
An X chromosome is known as an X chromosome based on its shape, which resembles an X. The Y chromosome resembles a Y.
The Y chromosome is larger and carries fewer genes than the X chromosome?
No. The Y chromosome is much smaller than the X chromosome. There are only about 70 active genes on the Y chromosome and many more deleteriously mutated one. The X chromosome contains many more active genes and only crosses over marginally with the 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.
How many times bigger is Antares than Pluto?
Bigger in what sense, mass or radius? The mean radius ratio is 300000000 km/1150 km, or about 260,000 times bigger.The mass ratio is 3.1 x 1031 kg/1.3 x 1022 kg, or about 2,400,000,000 times bigger.
Why does the y chromosome not carry any alleles?

This is why the Y chromosome does not carry any alleles in the same way that the X chromosome does.
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

Why are most sex-linked traits found in the X chromosome?
Most sex-linked traits are found on the X chromosome because males have only one X chromosome, so any gene on the X chromosome will be expressed in males. In females, who have two X chromosomes, one X chromosome can compensate for any harmful gene on the other X chromosome.
When a x chromosome is add is added to your mothers x chromosome what will you be?
A Male
