Fructose 16 vs. biophosphatase deficiency causes sudden death in infancy by increasing acidity of the blood and decrease in glucose level it affects boys and girls what is the only mode of inheritance possible how do you know this 

Answer 1

It's autosomal recessive. It's autosomal because it affects boys and girls equally (as opposed to X-linked traits which affects the sexes differently). It's recessive because, since it's fatal in infancy, it means parents must be able to carry it without actually having it.
