Consider two very distantly related species, Species A and Species B. These species live in distinct but similar environments and share a trait that improves their survival and reproduction in their respective environments. Which of the following is the most likely reason that Species A and Species B share this trait?
convergent evolution

convergent evolution

Explanation:

Convergent evolution is a process of evolutionary change that occurs when two different species, which are unrelated or do not share a common ancestral origin, evolve similar structures independently to become well adapted to their environments which are similar or have the same environmental conditions prevalent in them.

Convergent evolution is the opposite of divergent evolution. Organisms with different ancestral origin develop similar features and structures independently as a result of adaptation to similar environmental conditions. These structures are said to be analogous structures.

Examples of convergent evolution can be seen in hummingbird and the hummingbird moth, the streamline body shape of dolphins, etc.

Therefore, the most likely reason that species A and species B, that are unrelated, share similar trait but live in distinct environments that are similar is convergent evolution.

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)

not sure if this is what you'r looking for nnew= nold
