The figure shows a cross between 2 rabbits in rabbits black fur (B) is dominant to brown fur (b)

BbxBb

Top left B
Top right b
Left top B
Left bottom b
a brown
b black
c white
d speckled

The possible phenotypes (fur colors) of the offspring from this cross would be:

Bb (black)
Bb (black)
Bb (black)
bb (brown)

So, the possible genotypes/phenotypes are:

1. Bb - black
2. Bb - black
3. Bb - black
4. bb - brown
