Explanation:

In the context of evolutionary biology, coevolution refers to the evolution of at least two species, which occurs in a mutually dependent manner. ... An example is the coevolution of flowering plants and associated pollinators (e.g., bees, birds, and other insect species)

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)
