  1. The pattern of inheritance of sex-linked trait is criss-cross. The father passes the X linked allele of a trait to the daughters who pass it on to the grandsons. The father cannot pass a sex-linked allele to a son directly.
  2. The mother can pass the allele of a trait to both daughter and son.
  3. Only homozygous females can express a recessive trait, while heterozygous female are carriers and do not express the trait.
  4. Males express the trait immediately because of the absence of a corresponding allele. This is the reason why males suffer from sex linked disorders more than females.
  5. Most of the sex-linked traits are recessive. Some examples of sex-linked traits include Haemophilia or Bleeder’s disease, Daltinism or Colour blindness.
