How many times bigger is the x chromosome from the y chromosome?

∙ 12y ago
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.

∙ 8y agoThere are more genes on x- chromosome. y-chromosome has only a few genes but it helps in the determination of male gender. The size of the y-chromosome is smaller than x-chromosome because it has lesser genes.
Wiki User
∙ 13y agoNo, the X chromosome is much larger than the Y chromosome. :)
Wiki User
∙ 8y agoBecause x-chromosome has several genes on it whereas y-chromosome has very few.
Wiki User
∙ 12y agoApproximately 153,000 bp for the X chromosome.
Approximately 51,000 bp for the Y chromosome in humans. So about 3 times in humans.
Wiki User
∙ 9y agoThere are more genes on the Y chromosome than the X. A person can live without a Y but not without at least one X.

What is bigger E. coil bacteria or an X chromosome?
bacteria
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.
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 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.
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.
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.
Most sex-linked genes are found on which chromosome x y?
Many sex-linked genes are found on the X chromosome. More than 100 sex-linked genetic disorders have now been mapped to the X chromosome. The human Y chromosome is much smaller than the X chromosome and appears to contain only few genes.
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.
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
When a x chromosome is add is added to your mothers x chromosome what will you be?
