The X chromosome is stood on a yellow pages
The X chromosome contains considerably more genetic material than the Y chromosome.
female 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.
Everybody has 23 pairs of chromosomes, half they get from their mother and half from their father. The 23rd chromosome you have contains the information of what sex you are. If you are a girl you will have a X chromosome from your mother and and X chromosome from you father. If you are a boy it means you will have a X chromosome from your mother and a Y chromosome from your father. When a sperm cell fertilises an egg the sperm will either be carrying the X chromosome from the male or a Y. If the sperm is carrying a X it will pair with the X chromosome from the mother making the baby a girl. If the sperm is carrying a Y chromosome it will pair with the X chromosome from the mother making the baby a boy! This means it is all down to the father whether the baby is a boy or a girl.
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.
Yes, an embryo can develop with one X chromosome, rather than the XX or XY chromosome pair. An example of this is girls born with Turner's syndrome, who have only one X chromosome.
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.
An X chromosome is known as an X chromosome based on its shape, which resembles an X. The Y chromosome resembles a Y.
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.
In humans, the Y chromosome is noticeably shorter than the X chromosome.
An egg will have the X chromosome and the sperm will have an X or 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.
