Unless girls are taller than1.75m and boys are around1.7m, their offspring will be at least taller than1.7m..
In other words, if girls are not tall, considering the next generation, there must be requirements for boys' height!
The inheritance of Yan value should be called dominant genetic factor. For example, a high nose, big eyes and thick eyebrows, these obvious characteristics, no matter which parents have, will be passed on to their children. Therefore, even if a person's facial features are not good-looking, as long as he has a pair of big eyes and a high nose, it is already good.
Then if the woman has these characteristics, there is no need to be so strict with the man's face value, only the height condition is left!
A woman with beautiful dominant genetic characteristics, her requirement for boys is actually enough height! On the other hand, if the height is enough to balance the height of a boy, but a woman with general facial features, then she can find a boy who is not tall but has particularly beautiful facial features.
According to their own conditions, learn from each other's strengths. Of course, if God gives a perfect object, it must be the best!
