The correct answer is Sex-Linked character.

Key points:

  • Crisscross inheritance is shown by a sex-linked character from father to daughter and then from the daughter to her sons
  • The type of inheritance of recessive sex-linked character from father to daughter and then from the daughter to her sons is known as criss-cross inheritance or sex-linked or X-linked inheritance.

Additional Information

Crisscross inheritance 

  • When a male has a defective sex-linked gene located on the X chromosome he transmits the defective X chromosome to his daughter only during reproduction.
  • The female who has this gene transmits it to her son and daughter both in equal probability.
  • So the male passes on his recessive sex-linked trait to 50% of his grandsons through his daughter.
  • The sex-linked trait being recessive is not expressed in females but is expressed in males.
  • Therefore males suffer from the genetic defect due to the presence of a faulty gene on the single X-chromosome while females are the only carriers of these defective genes as they have the other X which masks the effect of the faulty gene
  • The trait shows up in females only both X chromosomes from mother and father have a faulty gene
