In generation 8 it would have 34 relatives, and in generation 9 it would have 55 relatives.
In the Fibonacci sequence, each term is found by adding the two previous terms together. For generation 8, we would add generation 7 (21) and generation 6 (13); 21+13 = 34. For generation 9, we would add generation 8 (34) and generation 7 (21); 34 + 21 = 55.
