Solution
The correct option is B A gene is passed down from father to daughter to grandson
Inheritance is the transmission of genes from parents to the offspring or from one generation to the next. When the genes are passed down from father to daughter to grandson, or from mother to son to granddaughter, the pattern of inheritance is referred to as criss-cross inheritance.
The speciality of this type of inheritance is that the genes are passed from parents to offspring of the opposite sex. A mother passes it to her son, who in turn passes it on to his daughter. Similarly a father passes it to his daughter, who in turn passes it to her son.
Hence, option b is correct.
