A relative of mine married his only daughter, but he says he is extinct and his line of succession is broken. Are his words justified?

No. Rather, it is a traditional old idea.

The blood relationship as understood by the people of China should be gene transmission from the perspective of modern biology. A child's genes come from both parents, not just from the paternal line.

In reality, we can see a lot of children look like their father in some places and their mother in others. This is the reason.

Grandchildren get a quarter of their genes from their grandparents. Another quarter comes from grandma.
