To find: the two reasons that the Fibonacci rabbit problem in example 1 is not realistic.

Answer to Problem 3CFU
It is not realistic.
Explanation of Solution
Given:
Fibonacci rabbit.
Concept used:
It seems to imply that brother and sister mate, which, genetically, leads to problems. it can get round this by saying that the female of each pair mates with any male and produces another pair.
Another problem which again is not true to life, is that each birth is of exactly two rabbits, one male and one female.
Calculation:
The two problems are:
One is genetically they get problems, because the brother and sister mate.
Two is each birth is of exactly two. That is one male and one female rabbit is not realistic.
Hence, it is not realistic.
