A gene that is found on the X chromosome and not the Y chromosome is a sex-linked gene. That is why men tend to get only certain diseases. For instance, certain types of color blindness are recessive and carried only on the X chromosome. So if the mother carries the gene, then if the father donates another X, thus creating a daughter, then she will likely not have color blindness, since the father's X chromosome should balance it out if he doesn't have color blindness. However, a son with the affected gene from the mother would be certain to get it since that is the only gene he has concerning the red and green vision receptors.
Traits like colorblindness, hemophilia, and Duchenne muscular dystrophy are carried on the X chromosome. These traits are caused by mutations in specific genes located on the X chromosome, such as the OPN1LW and OPN1MW genes for colorblindness and the F8 and F9 genes for hemophilia.
The genes carried on the X chromosome are called X-linked genes, while the genes carried on the Y chromosome are called Y-linked genes. These genes play a role in determining various traits and characteristics in individuals.
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.
Genes located on the X or Y chromosome are referred to as sex-linked genes. This is because the inheritance of these genes is dependent upon the sex of the individual. For example, only males can inherit genes located on the Y chromosome (because males have XY and females have XX).
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.

Genes that are located on the same chromosome are called linked genes. These genes tend to be inherited together during cell division because they are physically close to each other on the same chromosome.

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.
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.
according to the chromosome theory of inheritance,genes are carried from parents to their offspring on chromosomes.
The genes that are carried in the sperm to the ova. If the 23rd chromosome of the sperm is 'X', the offspring will be female. If it is 'Y', the offspring will be male.
X chromosome
Males transmit one set of sex chromosomes to their offspring. This includes either an X or a Y chromosome, which determines the sex of the child. Females always contribute an X chromosome.
