An example of a sex-linked trait is red-green colorblindness, which is carried on the X-chromosome. Muscle Muscle cells are specialized to generate force and movement. And that's because, since females have two X chromosomes, the chromosome that doesn't have a mutation can often compensate for the other X chromosome if it has a mutation.

The traits governed by these genes thus show sex-linked inheritance.

  • If a gene is found only on the X chromosome and not the Y chromosome, it is said to be a sex-linked trait. As the gene that expresses the trait is located on the sex chromosome, sex linkage is linked to the gender of the offspring.
  • Sex linkage describes the sex-specific patterns of inheritance and presentation when a gene mutation allele is present on a sex chromosome allosome rather than a non-sex chromosome autosome.

Examples of potential risk factors included prematurity, advanced maternal age, in vitro fertilization, congenital malformations, consanguinity, and a family history of CP or early stroke or heart attack at younger than 55 years. Replication stress can lead to CNV formation, and fragile sites.
