184440 When a cross is conducted between black feathered hen and a white feathered cock, blue feathered fowls are formed. When these fowls are allowed for interbreeding, in \(F_{2}\) generation there are 20 blue fowls. What would be the number of black and white fowls?

1 Black 20, white 10
2 Black 20, white 20
3 Black 10, white 10
4 Black 10, white 20
