When talking about race relationships, the Majoity in a relationship has

Power over the other.

Explanation:

The majority group have more numbers/population. This means that they are far more likely to vote the government officials who have the intentions to create legislations that benefited the majority group even though it might created layers of oppressions for the minority groups.

Because of this , the relationship between majority and minority group tend be massively unequal in terms of power/influence.

One thing that people from the majority group could shift this condition is by developing enough social awareness to learn and emphasize with the struggles that might be faced by the minority group. That's the only way both group can develop a mutual understanding with one another and wok together to create a society that is fair for both group.
