Color blindness is a recessive trait. the gene for the color blindness is on the x chromosome. the family tree below shows the trait of color blindness. the only unknown is the father in the first generation. what must be true about the father?

the father in the first generation probably had the recessive colorblind trait in his x chromosome. if he and his wife both had the colorblind trait, even if she had 1 recessive and 1 dominant, then that trait would be passed on to their kids.

(since you didn't attach the family tree this is just an assumption)

supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes
