Why do couples look alike?

Answer 1

People in a family don't look alike because your mom and dad both look different. And the reason the other members don't look alike is because your look is mixed together with your mom and dad's look.

Answer 2

Well most of the couples in anime look alike because many people can then guess that they're a couple or will end up a couple in the last episode. And also for some fun (so that the other anime characers can tease them). BEST EXAMPLE:
Dan & Runo from Bakugan Battle Brawlers
Their bangs are the same. They're the same height (clearly seen in scenes where they're arguing). They're the same age. They both lose their temper easy. They go in the same class(5E). (Althrough Runo wasn't seen in class.) They both like combinating cloathes that don't match; Dan combinates yellow and red and Runo yellow and pink. They also always say that they're not a couple. Their blood type is also the same (A).

Answer 3

There is a psychological phenomenon called assortative mating where people tend to choose partners who have similar characteristics to themselves, such as facial features or personality traits. This can contribute to couples looking alike over time due to shared genetics and environmental influences. Additionally, spending a lot of time together can lead to mirroring behaviors and expressions.
