One of the nurses describes a disorder by telling the group that it is common in children during the summer when it is hot or when the child is overdressed. which disorder is the nurse most likely referring to?

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)
