  • They always follow criss-cross inheritance

Solution

A.

They always follow criss-cross inheritance

Sex-linked characters are the X-linked characters. Their inheritance is due to the X-linked genes. The X-linked recessive characters follow criss-cross pattern of inheritance or skip-generation inheritance. In criss-cross inheritance, character is inherited to the second generation through the carrier of first generation.
