Sexual Relationships 
Sexual Health This is to answer a true or false question. The note that I have from my teacher on this is:
"The male sperm determines the sex of the future zygote.
The male donates either the X or Y chromosome.
The female's egg contains only XX chromosomes."
Would it be true or false, then, to state that the sex of the child is determined by its fraternal grandfather? The way I see it is:
True because sex is always determined by the male parent, and this goes back to the previous generation (s)
False because in the notes my professor has, it states that the sex of the child is determined by the father (not by any past generation)
Is sex of the child determined by its fraternal grandfather?

no it is only one generation to the next, and has nothing to do with the previous generations
It's determined by a random number generator that is DNA, X and Y chromosomes, and how much you drank that night if you really need it.
