Suggest why most plants die very quickly if their roots are cut off​

because plants are living things, and so if someone cuts you in half, then you're most likley gointnto die pretty quick. HOWEVER ur body will still most likley be moving because of adrenaline and left over energy.

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)
