Inheritance pattern

[magicsiew]

Mouse crosses:

Cross1: Females with normal tail crossed with male with long tail. All F1 offspring have long tails.

Cross2: Females with long tail crossed with male with normal tail. All F1 offspring have normal tails.

Cross3: F1 females from cross 1 are crossed to male with normal tail. All offspring have normal tails.

Cross4: F1 males from cross 1 are crossed to female with long tail. Half of the offspring have normal tail and half have long tail.

Any idea what kind of inheritance pattern is this?

Does sex have an effect?
Is there kind of dominance?

Are you lazy?

I think is sort of Non Mendelian Inheritance. But still dint get to draw out which 1 is it.

Not lazy, but rushing.

The answer is imprinting right?
