Help please!! What determinates that the seal is a water animal and that the bat is an air animal?​

A seal has flippers made for swimming, and a bat has wings made for flying.

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)
