In a guinea pig, curly hair (B) dominates over smooth (b). Determine the genotypes of all animals in the following crosses

In a guinea pig, curly hair (B) dominates over smooth (b). Determine the genotypes of all animals in the following crosses:
1) (females) with curly hair х (husband) with smooth -> all descendants with curly hair;
2) (females) with curly hair x (male) smooth -> 1/2 offspring with curly hair, 1/2 – with smooth;
3) (females) with smooth coat x (male) with smooth -> offspring are always only smooth-haired.

1) (women) – BB; (husband) – bb.
2) (women) – Bb; (husband) – bb.
3) (women) – bb; (husband) – bb.
