Sex-linked traits are associated with genes found on sex chromosomes. In humans, the sex chromosomes are X and Y. Because the X-chromosome is larger, X-linked traits are more common than Y-linked traits. An example of a sex-linked trait is red-green colorblindness, which is carried on the X-chromosome.
How are sex linked traits inherited give examples?
Sex-linked diseases are passed down through families through one of the X or Y chromosomes. X and Y are sex chromosomes. Dominant inheritance occurs when an abnormal gene from one parent causes disease, even though the matching gene from the other parent is normal.
Are sex linked genes traits important to know why?
Biological Basis of Heredity: Sex Linked Genes. A particularly important category of genetic linkage has to do with the X and Y sex chromosomes. These not only carry the genes that determine male and female traits but also those for some other characteristics as well.
