Yes, double first cousins are considered first-degree relatives. This occurs when two siblings from one family each marry two siblings from another family, resulting in their children sharing both sets of grandparents. As a result, double first cousins have a closer genetic relationship than regular first cousins, sharing about 25% of their DNA, similar to that of half-siblings.
Does a first cousin have a close genetic relationship?
No. First cousin share 1/8 of your variable genes and only 1/32 with second cousins. With third cousins you share only 1/128.

It is often expressed as a percentage, indicating how much of their genetic makeup is identical due to common descent. For example, siblings share about 50% of their genes, while first cousins share about 12.5%. This concept is important in fields such as genetics, evolutionary biology, and conservation.
