Answer:
The genotype of all offsprings would be "Bb"
Step-by-step explanation:
The two parent rabbits between which the cross is carried out have the following genotype
Parent I - Homozygous dominant "BB" with brown fur
Parent II - Homozygous recessive "bb" with white fur
The cross between these two can be represented by a punnet square
B B
b Bb Bb
b Bb Bb
All the offsprings produced are heterozygous with genotype "Bb"
