Predict the fur color of the offspring of a brown heterozygous rabbit and a white homozygous rabbit. brown is dominant and white is recessive. use b for dominant and b for recessive.

what are the genotypes and phenotypes of the new generation?

what are the percentages of brown and white rabbits?

To predict the results of the offspring from a cross between brown heterozygous rabbit and a white homozygous rabbit, a punnet square can be drawn as follows:

        b        b

B   Bb         Bb

b   bb         bb

The results from the punnet square show that there is 2:2 ratio that the offspring will be brown coloured or white coloured. The genotype of the rabbits will either be heterozygous brown i.e Bb or homozygous white bb.

there is a 50% chance that the offspring will be brown rabbit and there is also a 50% chance that the offspring can be a white rabbit.
