If an individual has the chromosome series XY, that individual would be a male. The Y chromosome is passed down from the father and the X is passed from the mother. The X chromosome contains all hereditary factors while the Y chromosome doesn't contain much genetical information at all, except the fact if Y chromosome is present that individual will be a male. This is all only true for Humans. Dosophilla (fruit flies) have different chromosomal expressions.
What else can I help you with?
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 X chromosome affect an organisms phenotype more than the Y chromosome?
The X chromosome contains considerably more genetic material than the Y chromosome.
Why does a sex-linked trait only require one recessive allele on the X chromosome of a male to show the phenotype?
Because males have only one X chromosome, any recessive allele present on that X chromosome will be expressed in the phenotype. In females, who have two X chromosomes, the presence of a dominant allele on one X chromosome can mask the expression of a recessive allele on the other X chromosome.
Which type of chromosome does the female parent give to it's offspring?
The female parent contributes an X chromosome to its offspring. In humans, females have two X chromosomes (XX), so they can only pass on an X chromosome. If the offspring receives an X chromosome from the male parent (who can contribute either an X or a Y chromosome), the offspring will be female (XX); if the offspring receives a Y chromosome from the male, it will be male (XY).
Can an embryo develop with one x chromosome?
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.
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.
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
When a x chromosome is add is added to your mothers x chromosome what will you be?
A Male
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.
What chromosome does hemophilia come from?
The X Chromosome.
Which chromosomes from the sperm is necessary to produce a male?
x 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.
In humans a male has?
One X chromosome and one Y chromosome, which determines male sex characteristics.
On which chromosome is the human gene known as Factor X located?
The Factor X gene is said to be located on the X chromosome. Females have two X chromosomes, whereas males only have one. The other chromosome they have is a Y chromosome.
