Question

what is the difference between 2nd cousin and 1st cousin once removed

In: Biology

Answer 1

Your first cousin is the child of your aunt or uncle.

Your first cousin once removed is a person who is the first cousin of one of your parents. (They are ‘once removed’ because you are separated by 1 generation-level from being first cousins.)

If your first cousin once removed had a child, that kid would be your second cousin because you’d both be on the same generational-level (with your parents being first cousins).
