Answer: 1/4
Explanation:
Firstly, in order for both parents to be type A and have children with type o blood, their blood types must both be Ao. Since o is a recessive blood type, a punnett square shows there is a 25% chance any child of theirs will have type o blood. If neither parent is color blind and they have a son who is, it implies that the mother is a carrier of colorblindness and has the genotype XᴮXᵇ. If you do a punnett square of the not colorblind father (XᴮY) and the mother, it shows that a daughter would have a 0% chance of being colorblind. Therefore colorblindess is irrelevent, since there is no possibility of the daughter not having normal color vision. In conclusion, there's a 25% chance she will have type o blood and not be colorblind, since the other 75% chance would be having type A blood and not being colorblind.

Answer:
OB) An elephant in the savannah develops without the ability to hear. A salamander living in a cave is born without, eyesight or fully developed eyes.
Explanation:
Adaptations are gradual modifications and changes in the physical characteristics or behavior of an organism, so that it could facilitate the survival of the organism in that particular environment.
In case of elephant without ability to hear specially in the regions of Savannah where there is vast grasslands with scanty vegetation and animals, then the elephant can't hear any sound of danger like approaching calamities, also it could hear the call of other elephants, in case if the elephant becomes segregated.
In salamander, low eyesight or low vision will further add to the misery, as there is already darkness in the cave. It could fall prey to any predator or it could not be able to feed on consumable organisms as it could see properly.
