Which statement about inheritance is true?
girls get most of their traits from their moms; boys get most of their traits from their dads.
male offspring will always have an x-linked genetic disease if the mom is a carrier.
fathers always determine the gender of the offspring in humans.
males never have y chromosomes.

The correct answer is option Fathers always determine the gender of the offspring in humans.

In case of the humans, the females have two X chromosomes and the males have one X and one Y sex chromosome. So, the female always contribute X chromosome to the gamete. The female always produce the same type of gamete in any case. The males either pass X chromosome or the Y chromosome. In case, the gamete with the X chromosome fuses with female gamete than the progeny would have XX chromosome and will be a female. In case, the gamete with the Y chromosome fuses with female gamete than the progeny would have XY chromosome and will be a male. Hence, teh fathers determine the gender of the child.
