Based on the given Punnett square:
Top left: Bb
Top right: bb
Left top: Bb
Left bottom: bb
From the Punnett square, we can see that there are 2 rabbits with the genotype Bb and 2 rabbits with the genotype bb.
Therefore, the genotype ratio of the F1 generation is 2:2, or simplified, 1:1.
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
what is the genotype ratio (BB:Bb) of the F1 generation? Use the above punnett square
