What chromosome are found in males only?
Y i think
What is more likely to happen to males because they have only one X chromosome?
sex-linked disorders
Where is a human X-linked gene found?
A Y-linked gene is a gene that is carried on the Y chromosome, a sex chromosome found only in male cells. In humans, the most commonly mentioned Y-linked gene encodes a protein called testis-determining factor (TDF). As the name suggests, TDF prompts the development of the testes. Since only genetic males have a Y chromosome, only males express TDF and go on to develop testes. In general, genes carried on the sex chromosomes (X and Y) are considered to be "linked" to that chromosome. Genes carried on the X chromosome are considered X-linked in the same way that TDF is considered Y-linked.
What are sex-link genes and their effects?
Since males are the only sex to have a y chromosome, only males can get genes that are linked to the Y chromosome. This means that some genetic diseases and conditions are more likely to be male such as color blindness.
A recessive gene located on the X chromosome is the cause of hemophilia in affected individuals. Males are more likely to have hemophilia than females because?
Males only have one copy of the X chromosome

what cell contain only one sex chromosome?
In males, sperm contain only one sex chromosome. In females, eggs contain only one sex chromosome.

Why is colorblindness found to be inherited into males more than females?
Most color deficiencies are sex linked, meaning the defective genes are on the sex chromosome. In this case, the X chromosome is affected. Since males only have one X chromosome, all males with this particular defective genes will have this condition. Females have 2 X's, it's unlikely that both X's have bad genes at the same time.
Why is the y chromosome useful for tracing ancestry?
The y-chromosome is only present in males. Men will a y-chromosome identical to that of their father, and his father, and his father, etc.
Fragile X syndrome affects only females?
No, Fragile X is on the X chromosome. Females have 2 X chromosomes and Males have an X and a Y Chromosome. Therefore, both males and females can have Fragile X (they can have the full mutation or be carriers). Males are usually more severly affected because they have only one X Chromosome.
Why does wiskott aldrich syndrome only affect males?
I believe because it is linked to genetic x-chromosome sex-inherited trait, females have another x-chromosome whereas males do not
Why are males more likely to have fragile X syndrome?
males have only one copy of the X chromosome. Males who inherit the full mutation are expected to have mental impairment. A female's normal X chromosome may compensate for her chromosome with the fragile X gene mutation
Who determines the sex of a child?
The generally accepted theory is that males determine the sex because males can donate both an X chromosome or Y chromosome, while females can only donate an X chromosome to their offspring :D Hope this Helped
What cell contains only one sex cell?
In males, sperm contain only one sex chromosome. In females, eggs contain only one sex chromosome.
Chromosomes found in somatic cells and are perfectly matched in males and females?
In both males and females there are 22 perfectly matched chromosomes. The somatic cells in humans total 46 chromosomes. Females get the XX sex chromosome while males get the Y chromosome.
