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 else can I help you with?
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.
How you can distinguish y from the x sperm?
Size, generally. The X chromosome looks like an X and is smaller than the somatic chromosomes. The Y chromosome is a shrimp, comparatively, so it is always easy to spot.
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.
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.
Men have one of y?
The y chromosome. The chromosome pair that determine sex (gender) can have x and y chromosomes; men have one X and one Y chromosome, women have to X chromosomes.
What portion of the human Y chromosome is homologous to the human X chromosome?
The pseudoautosomal regions (PARs) at the tips of the Y chromosome are homologous to regions on the X chromosome. These PARs are responsible for pairing and recombination between the X and Y chromosomes during meiosis. About 5% of the Y chromosome is homologous to the X chromosome in humans.
Can a male have the same X chromosome as his paternal grandfather?
No, he cannot.He cannot even have the same X chromosome as his father.The reason is that a male has an X and a Y chromosome in his genome. The Y must come from Dad, because Mum does not have any Y to pass on!So the X must come from Mum.Now looking at grandparents: a male's father supplied the Y, and father's Y came from the paternal grandfather. So the paternal grandfather's contribution must be the Y chromosome.The male's Mum has two X chromosomes, one from the maternal grandfather, and one from Mum's Mum.
In humans a male has?
One X chromosome and one Y chromosome, which determines male sex characteristics.
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.
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.
Why does the X chromosome affect an organisms phenotype more than the Y chromosome?
The X chromosome contains considerably more genetic material than the Y chromosome.
How do X and Y chromosome differ?
The X chromosome is larger and carries more genetic information than the Y chromosome. The Y chromosome carries the genes that determine male sex characteristics, while the X chromosome carries genes that are important for both male and female development. Males typically have one X and one Y chromosome, while females have two X chromosomes.
