6. In humans, hemophilia is a recessive and sex-linked character. A man and a woman (grandparents), both normal with respect to blood clotting have: 1 a hemophilic son who has a daughter who is normal; - a daughter who has normal blood and who has one hemophilic and one normal son; and - another daughter with normal blood who has five sons, all normal.

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
