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.

A horse breeder must confirm the lineage of a new foal in order to submit its pedigree. The diagram below shows DNA fingerprinting from the foal and its assumed father, Steeplechase. Which conclusion can you draw?

The foal definitely was not sired by Steeplechase.

The foal definitely was sired by Steeplechase.

It is unlikely that the foal was sired by Steeplechase, but further testing is needed to be certain.

The lack of matches indicates that the test is corrupted; a new test will have to be performed.
