In rabbits, fur color and ear position are two genetic traits. The allele for producing brown fur (B) is dominant to the allele for producing white fur (b). The allele for producing straight ears (E) is dominant to the allele for producing floppy ears (e).
Two rabbits that have the phenotype of brown fur and straight ears and the genotype (BbEe) were crossed. Use the completed Punnett square below to determine the probability of offspring that have white fur and floppy ears.
