20. What is the best explanation for why the change in temperature is different for the each of the colored boxes? *

Dark surfaces become warmer because they absorb more of the incident radiation. Light-colored surfaces reflect more of the incident radiation, hence absorb- ing less radiation. The higher the absorption, the warmer the temperature.

Explanation:

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)
